@Japan Fine Ceramics Center (JFCC) developed excellent gas seal material for SOFC, which is composite made of silica precursor particles and silicate glass precursor particles, and it is superior in hest cycle endurance under heating and cooling cycles. When it is heated at the heating rate of more than 20Ž/s, it still retains good gas seal and gas leakage is not observed. The material is highly flexible sheet and melted at about 800oC. Under 500 times heat cycles between 800Ž and 400Ž leakage was not found. Optimizing ratio of the two particles and melting conditions, JFCC succeeded in retaining gas seal characteristics under quick temperature increases. JFCC is going to further development and real use for highly stacked SOFC endurable under quick start up. [The Denki Shimbun (electricity) July 2, 2009]

5. PEFC Elementary Technologies Development
(1) National Institute for Materials Science
@The above institute and Japan Science and Technology Agency developed technology to make about twice increase of platinum particle surface of 20 nm size usually used as catalysts. The developed catalysts are particles with projections of several nm size on the surface to increase it. When ascorbic acid is added into solution of platinum and surface active agent, platinum is formed but it is not formed on the platinum particle surface with the surface active agent. Platinum is formed only on the surface without the surface active agent. After 10 minutes about 20 projections of 2 - 3 nm size are formed on a platinum particle of 20 nm in diameter. Thus surface area of the platinum becomes 55 m2 per 1 g. and it is 2 times larger than conventional ones. They intend to real use as catalysts for FC and exhausted gas cleanup. [The Asahi Shimbun June 24, 2009 and The Nikkei Sangyo Shimbun (economy and industry) June 25, 2009]

(2) Tokyo Institute of Technology
@Prof. Yamaguchi and his group in the above institute developed membrane of long endurance, in which hydrogen ion permeates even in low humidity. Electrolyte material is impregnated into polyimide film with nm size pores. Hydrogen and oxygen do not permeate the membrane, but hydrogen ion does. Zirconia particles are winded with polyelectrolyte and it is inserted into polyimide film at every 20 - 100 nm interval. For conventional membrane humidity should be controlled up to 90%, but in this membrane hydrogen ion can permeate even at 50 - 90% humidity. The pores are filled, so that water cannot go in. [The Nikkan Kogyo Shimbun (bjsiness and technology) July 6, 2009]

(3) Sumitomo Metal Industries, Ltd.
@The company established separator technology, by which inexpensive separators can be made using stainless steel foil at price for propagation. The press molding cost per sheet (about 100cm2) is made cheap, namely down to 100 - 150 yen. The material cost of stainless steel and the total cost including sealing can be reduced to several hundreds yen The sizes of trial products are 7 cm wide and 14 cm long. The press molding can be done successively, and the production rate can be made 60 sheets/min. The mold can also be used 150,000 times without maintenance. Thus the cost related with molding has been reduced below 100 yen/sheet, including the initial cost, the maintenance cost and the operating cost. The test products have already been shipped to FC makers. [The Nikkan Kogyo Shimbun (business and technology) July 17, 2009]

(4) National Research Institute for Advanced Industrial Science and Technology
@The above institute has been carrying out development of new electrode catalysts of high CO endurance., and it has succeeded in preparation of carbon fine powder catalyst with noble metal molecular sieve. .The structure has been analyzed and hydrogen adsorption is also evaluated. Molecular sieve of nano-carbon with micro-pores of 0.2 - 0.35 nm was used. They are aiming to make innovative catalysts in which CO does not adsorb on active platinum and they have excellent CO endurance. In 2008 fiscal year they prepared catalysts in which about 12 nm noble metal fine powder is dispersed in micro-fine carbon molecular sieve. By structure analysis and hydrogen adsorption evaluation, it was demonstrated that hydrogen adsorption does not decrease even in 400 ppm CO concentration. Hereafter, change of CO endurance is going to be tested and evaluated. Furthermore, they intend to establish catalyst technology for catalyst, which shows the same activities even in 500 ppm CO concentration as conventional ones. [The Chemical Daily July 16, 2009]

6. Business and Elementary Technologies Development of Home Use Enefarm
(1) Yamanashi University
@On June 26, 2009 Nano-Materials Research Institute of the university announced that it developed high performance catalyst for Enefarm reformer. With the new catalyst residual CO can almost perfectly be removed. Moreover, the manufacturing cost of the fuel reformer can be reduced by 20%, and the size of the reformer is decreased to 2/3. The newly developed catalyst for CO selective methane formation is made as follows; amorphous nickel aluminate of high surface ratio was made by unique technique and on its surface nickel nano-particles were deposited. The nickel nano-particles have high CO removing characteristics and side reactions are hard to occur. By this nickel deposition low temperature characteristics are also improved. With this catalyst over 99.9% CO was removed even in high CO concentration of 0.6 - 1.0%. By effect of added ruthenium high temperature characteristics are also improved, so that temperature range for using catalyst became wide, 200 - 300oC. Thus the reformer can be operated in stable state. Because CO is converted to methane using hydrogen, air for selective oxidation became unnecessary. Thus the structure of the reformer became simple. Metal honeycomb structure of high thermal conductivity is used for catalyst materials so that used catalyst reduced to 1/5.

[The Hokkoku Shimbun and The Toyama Shimbun July 3, 2009]

(2) Hiroshima University
@An Associate Prof. Nakajima of Hiroshima University developed technology to produce hydrogen and ethanol from wasted oil in bio-diesel fuel (BDF) producing process. Bacteria producing hydrogen were separated from methane fermentation microbes, which produce methane gas from sewage etc. These bacteria were cultivated to form mutants and they succeeded in obtaining bacteria for producing hydrogen and ethanol by decomposing BDF glycerol. The bacteria was named "Enterobacter aerogenes HZU101". In exhausted liquid containing glycerol, amino acid etc. were added for promoting reaction, and then hydrogen and ethanol were formed. BDF 930 L was produced from plant oil 1000 L, and exhausted liquid containing glycerol 200 L was formed. By applying the present technology, hydrogen 145 m3 (0Ž and 1 atmosphere) and ethanol 48 L were formed. In general exhausted liquid was burnt in conventional process, but more efficient use becomes possible by the present technology. [The Nikkei Sangyo Shimbun (economy and industry) July 3, 2009]

10. Technology Development of Hydrogen Transport and Storage
(1) Kurimoto Ltd. and Ryukoku University
@In collaboration, the above two have developed technology to decrease hydrogen releasing temperature by 80Ž to 220Ž in magnesium base hydrogen storage alloy. By using a planets ball mill, a unique one by Kurimoto Works, shocks of 150 G (acceleration of gravity) were added to magnesium hydride and alumina to form hydrogen absorption alloy of fine structure. In fine alloy formation with the mill, it takes 3 - 12 hours, but by large mechanical energy loaded in the new process and addition of alumina to promote crashing, the treating time was reduced to 10 min. In the new alloy structure, alumina is several hundreds nm in diameter and magnesium hydride is 10 nm in diameter. Nm level fine particles formation seems to decrease the temperature. Detailed mechanism will be investigated in the future. Nm size fine particle formation seems to activate the particle surface and thus to change the activation energy. The hydrogen absorption capacity of magnesium alloy is about 7% of the alloy mass, and it is larger than that of lanthanum - nickel alloy (about 1.3%). Hereafter, the temperature is tried to decrease by adding catalyst to about 150Ž and they anticipate real use in 2012 fiscal year.

(2) FuseTechnoNet Co. and Nagaoka University of Technology
@In cooperation the company in Tokyo prefecture and the institute are going to develop new hydrogen storage materials, which can store and release hydrogen efficiently, using carbon from chaff. The development will be made by March of 2010. Active carbon of micro-fine pores is made in large amount from rice chaff. Silica surface on the chaff carbon is dissolved in alkaline solution, so that micro-pores inside the carbon appear on the surface. Thus the surface area of this carbon is more than 2000 m2 per 1 g of carbon, and it is the optimized structure for storing and releasing hydrogen in large amount. For FCV 10,000 L of hydrogen should be stored. Using this new carbon, about 30 kg carbon can store this amount of hydrogen. [The Nihon Keizai Shimbun July 9, 2009]

11. Development and Business of Micro-FC
@Sanyo Special Steel Co., Ltd. is carrying out development with Hokkaido University in cooperation, and the company is hastening the development. The technology under development is to increase the output by changing structure of separators in small DMFC for portable equipments etc. The company is now shipping samples to makers. It is based on technology developed by cooperation with Hokkaido University in September of 2007. For channels on separators sponge-like porous metallic material is used, so that oxygen etc. flow uniformly, and thus the maximum output increases by 30 - 40% compared with conventional ones. In the newly developed separators spherical stainless steel materials are sintered and used. Thus choke of water, CO‚Q etc., un desirable by-product for generation, is hard to happen and the efficiency is increased By tests the output density of 134 mW per 1 cm2 of separator was recorded. Thus it increases three times compared with conventional ones and it is over the target by NEDO. [The Nikkei Sangyo Shimbun (economy and industry) June 23, 2009]

12. Metrological Development and Business Related with FC and Hydrogen
@In collaboration with Prof. Kubo and his group of Okayama University, Kuramoto Co. in Kurihara city developed organic transistors using pithene (hydrocarbon). The mobility in world highest level (5cm2/V/s) is one of features. The company developed gas sensors together with Ideal Star, a firm for R&D in Sendai city. It was confirmed that pithene works in the room temperature, and it is possible with a sensor to measure concentration of hydrogen simultaneously with temperature and oxygen concentration.. A trial chip is small and 2.5 cm square, and it can be assembled in electronics board. The superior points are small, light, low voltage and energy saving. The company is looking for applications to FCV, gas alarms etc. [The Kahoku Shimpo July 1, 2009]
