4.Commercialization of MCFC
FCE (FuelCell Energy Inc.) and IHI (Ishikawajima-Harima Heavy Industries Co., Ltd.), only the two companies are in commercialization stage of MCFC in the world. 
Marubeni Corporation who has concluded sales agreement with FCE, has delivered 5 units of 250 kW MCFC so far, fabricated by FCE. The first unit has been delivered to Toride Factory of Kirin Brewery Co., Ltd. and the second to Hukuoka City, fueled anaerobic digester gas produced during swage treatment. And another two have been delivered to Seiko Epson Corporation, which were advanced type for natural gas fuel. Further, two units using anaerobic digester gas produced from food wastes will be introduced in Tokyo and Kyoto Prefecture. FCE has delivered another 16 units in the USA and MTU, subsidiary of Daimler Chrysler in Germany, has delivered 8 units. FCE has commercialized 1000 kW and 2000 kW based on the 250 kW and the first 1000 kW has been constructed in swage treatment center in Washington State and will be operated in May. And the 2000 kW plant is under construction, combined with coal gasification. Marubeni will put these 1000 and 2000 kW plants on market and made a policy to shift the business to a new subsidiary, making use of merits such as high power generation efficiency of 47 % even in case of anaerobic digester gas and low stack replacement cost of 1/2 ∼ 1/3 in comparison with PAFC. 
On the other hand, IHI has manufactured two 300 kW MCFC, to be introduced by Chubu Electric Power Co., Inc. and Toyota Motor Corporation into Aichi International Exposition, and been conducting the demonstration operation. Chubu uses anaerobic digester gas produced from garbage using low temperature methane fermentation reactor and Toyota uses fuel being gasified wooden waste and waste plastics and adopts combined cycle with micro gas turbine. IHI intends to enter the commercialization stage in case the demonstration operation in Aichi International Exposition will be successful.

5.Research and Development of SOFC
(1) CRIEPI (Central Research Institute of Electric Power Industry)
CRIEPI announced that they obtained a prospect to develop all ceramics SOFC without using metal parts even for connection. They improved the durability which they extended the continuous operation up to 2000 h under operating temperature of 1000 Ž and realized the output density of 1 W/cm2. Degradation used to be occurred by chemical reaction in case of connection between two ceramics and cracks would be generated by the difference of thermal expansion in case to connect different kind materials including metal, which results in leakage of hydrogen or air. They made water solution like mud by adding inorganic oxide material such as calcium oxide and they made uniform membrane of 10 ƒÊm thickness on the electrode surface to suppress chemical reaction and then they connected power generation parts each other. They have improved the durability by resolving conventional problems by the above procedure. They are expecting the application to PEMFC including home use or automobile.

(2) Kyocera Corporation
Kyocera intends to complete 1 kW class home use SOFC system with net efficiency of 40 % (HHV) by October 2004 and start long time durability test and launch monitor sales of pre-commercial unit in 2005 under cooperation with energy company. Although they have started a commercial use SOFC of 5 kW to be commercialized in 2007 under cooperation with Tokyo Gas Co., Ltd., they will set up system of home use SOFC to be commercialized at the target price of 1.2 million yen/kW for the time being and conduct durability test. And then, they will realize the cost reduction down to 600,000 yen/kW. They will evaluate the load following speed without reduction in power generation efficiency, partial load efficiency, necessary procedure for start and stop of the plant and the operation cost of the system. Further, they have verified power generation efficiency of 50.3 % (HHV) and 54 % (LHV) as the cell performance under operating temperature of 780 Ž.

(3) Toho Gas Co., Ltd.
Toho Gas intends to start mass production of SOFC single cell jointly developed with Nippon Shokubai Co., Ltd. within 2004. They have resolved the problem of the fragility and improved the power generation performance and the durability by adopting scandium oxide stabilized zirconium oxide as the electrolyte material which has both high tenacity and electrical conductivity. This type of FC has a feature to be able to conduct mass production at low cost because the FC does not use platinum. The production cost is cheap because the electrolyte production process is to mix binder with powder material and cast the sheet and then sinter it which is the same as general ceramics sintering process. Toho Gas is in charge of material development and Nippon Shokubai submits know how on mass production. And they cooperate to manufacture and sell the SOFC.

6.Development of Elemental Technologies for PEMFC
Professor Kijima et al., Department of Engineering, Miyazaki University developed the technology to make a nano-tube of 10nm or less in the outside diameter by using metal or phenol resin. It is expected that the performance of FC could be improved by applying the nano-tube for the electrode or the electrolyte of PEMFC. The feature is to utilize a surface active agent. The platinum nano-tube of 6nm in outside diameter, 3nm in inside diameter and several 10 – 100 nm in length, has been obtained by adding two kinds of surface active agents to the solution of the chloride platinic acid and making it into the liquid crystal state and then reducing it.

10.Development of Hydrogen Storage Technology
Special Researcher Matsuura, Senior Researcher Tanigawa and Deputy Director Kokaji, Intelligent Systems Institute, National Institute of Advanced Industrial Science and Technology (AIST) have developed a fundamental technology to produce hydrogen storage polymer from alcohol.
The technology is to pour liquid alcohol on the anode surface and to irradiate electron beams to the anode from the needle tip of the cathode located at the other side of the anode and then polymer including hydrogen ion is produced and formed on the cathode, with rising flow generated from the liquid surface of alcohol by cracking the chains of both carbon and hydrogen atoms. It is reported that approximately 20ƒÊm in width, 50ƒÊm in length, 10ƒÊm in thickness polymer was formed on the cathode in a few seconds when 800 eV electron beams were irradiated in the atmosphere of 26Ž, 50% relative humidity using butanol as alcohol. As the results of analysis for the polymer by using infrared rays, they found that the polymer is consisted of entirely different chemical structure by being cracked the chain of the butanol molecules and re-connected irregularly.
Hydrogen can be preserved in the ionized state and also taken out easily only by electrical stimulus given to the polymer. The experiment showed that hydrogen could be taken out only by giving around 6V, 50Hz electric stimulus to the polymer. The technology is expected to be applied to the hydrogen storage not only for FCV but also FC for mobile equipments as the ion consisting the polymer does not have little risk of ignition.
These results will be reported in gJournal of Physical Chemistryh on April 29, 2004.
