1. Research and Development in SOFC - Anode Material
    CRIEPI(Central Research Institute of Electric Power Industry) found optimum composition rate in anode material of SOFC. Although mixed powder of Ni and YSZ have been used so far, CRIEPI found that stability of anode material in long term power generation can be obtained by mixing Ni powder with coarse and fine particle of YSZ. They said that following ratio is the best for long life of SOFC and initial performance can be kept even after 2000 hr operation.
   YSZ(coarse particle) : Ni : YSZ (fine particle) = 4 : 6 : 1 or 5 : 5: 1    They have next research plan to evaluate optimum particle size for each material.

2. Technical Development in PEFC - Separator Technology
    Hitachi Research Institute of Hitachi,Ltd. announced that they developed a manufacturing technology of PEFC separator which is light and low cost. Thickness is one tenth and the weight is a half in comparison with conventional by changing the material from graphite to metal with high strength. It is expected that processing becomes easy because of metal and the cost becomes a half. In case of metal, surface treating like gold plating has been needed in order to avoid corrosion and it results in high cost. However, feature of this technology is to use thin clad plate coated by special metal durable for corrosion of steel or copper and also over laid by paint having characteristics of anti-corrosion and electrical conductivity. Coating material is not published for the time being. Hitachi tried to fabricate prototype product of 1.2 kW for domestic application and the weight is a little less than 10 kg and it resulted in 30% reduction of weight.

(1) BMW Group
    BMW completed a Bi-Fuel Car 745-h which burn both hydrogen and gasoline in an internal combustion engine. They intend to start the sales after several years. They will exhibit the car at Tokyo Motor Show publicly opened from October 26, 2001. The car is more finished in comparison with hydrogen car they made 15 in last year and also hydrogen tank is far compact in size. 5 kW SOFC will be installed as auxiliary power source and the SOFC is operated by hydrogen made by gasoline reforming. The operating temperature of gasoline reforming and SOFC are both high temperature of 900 ‹C. Therefore, there might be some subject to overcome in the material, however, they expect to be commercialized far earlier than PEFC.

(2) National Institute of Advanced Industrial Science and Technology (AIST)
    AIST Synergy Material Research Center has succeeded to confirm the basic function of hydrogen gas sensor which detects only hydrogen at room temperature. The sensor consists of thermo-electrical converting membrane and platinum catalysis membrane which is formed partially on the thermo-electrical converting membrane. The principle of function is that, the temperature difference by heat generation of hydrogen reaction with catalysis membrane is converted thermo-electrically to electric voltage signal. Tested thermo-electric converting sensor made of nickel oxide added lithium generated 0.15mV voltage signal for 1% hydrogen mixed with air. As the converter generates electric voltage proportionally to hydrogen concentration the sensor can be utilized not only for hydrogen gas sensor but also hydrogen concentration meter.
    Functioning at room temperature and low electric power consumption, the sensor can be integrated with silicon chips and is expected to be utilized for the safety measures in FC operation. AIST, when it becomes practicable, is considering materialize this technology within a couple of years. Conventional hydrogen sensor converts electric resistance to the signal, which varied with reaction of hydrogen and oxygen adsorbed on surface of tin oxide. And conventional sensor has such shortcomings to have to heat up to about 400 ‹C and also to sense methane and carbon monoxide.

6. Fuel Related Technology
(1) Nippon Steel Corporation, NKK Corporation etc.
    The Japan Research and Development Center for Metal (JRCM) will start a cooperative R & D project within this year with NSC, NKK and others, to generate hydrogen with low cost from coke oven gas of hydrogen and methane rich. Iron and Steel Companies usually generate by-product gas such as coke oven gas, blast furnace gas, converter gas etc., and coke oven gas contains 50% hydrogen and 30% methane. Coke oven gas is, now, cooled down from 800 ‹C to 80 ~ 100 ‹C by ammonium water spray to separate impurities such as tar from hydrogen and methane gas and utilized as fuel for heating furnace or others. This cooling process loses a lot of heat. In this project, NSC will provide ceramic membrane technology used for oxygen separation from high pressure air heated by 800 ~ 950 ‹C exhaust heat from the steel production process. The generated oxygen reacts with methane contained in coke oven gas or LNG and hydrogen is produced. Establishing the technology for hydrogen mass production with lower cost than conventional, finally the commercialization is expected. Teikoku Oil also participates for this project. The feature of the production technology to be developed by this cooperative project is to combine two processes utilizing methane reforming by high temperature steam and catalyst and partial oxidation using produced oxygen. In steam reforming process, reaction becomes inactive by temperature decrease with endothermic reaction and it is covered by heat from exothermic reaction of partial oxidation. Organizing a National Project subsidized by Ministry of Economy, Trade and Industry, a bench scale plant will be developed by 2005. NSC states that "will establish energy business selling hydrogen as a chemical resource" when the project is successfully concluded.

(2) Japan Science and Technology Corporation (JST) and others     A cooperative research team organized with JST, Prof. Sumio Iijima of Meijou University, Prof. Katsumi Kaneko of Chiba University, NEC Corporation and Institute of Research and Innovation discovered that single layer nanohorn can storage 160 times methane in volume. By heat-treating single layer nanohorn at 400 ‹C under oxidizing atmosphere, nanohorn has nano-size fine pores and increases its surface area. In case of ordinary nanohorn, gas can flow through only conical opening, but in case of nanohorn having fine pores, gas can flow through also fine pores and methane gas is changed into super critical liquid by interference of methane molecule and nanohorn wall including fine pores even at room temperature. It is understood that these mechanism make nanohorn possible to storage methane in high density. To utilize this technology for fuel tank of FCV is expected.

(3) NKK Corporation
    NKK announced that NKK and 7 companies including Toyota Tsusho Corporation, Hitachi,Ltd., TotalFinaElf-French major oil company, Marubeni Corporation, Idemitsu Kosan Co.,Ltd., , INPEX Corporation and Nippon Sanso Corporation agreed to jointly establish a feasibility study company "DME International" for production and marketing of DME produced by direct synthesis technology on October 19, 2001. 3 groups have been developing DME production technology by direct synthesis, in the world. With high efficiency and the progress of development, NKK developing process is noticeable, and expected to be applied to utilization of vast low grade coal reserved in Asian region and marginal gas field. As the development of DME production technology by direct synthesis reached to the stage to carry out concept design of demonstration plant, this feasibility study company will arrange to start DME business just after development is concluded. The business scale with 800,000 - 1,500,000 ton annual production by 2006, is expected.
