(1) Ministry of Economy, Trade and Industry
METI announced on February 18 that they clarified their policy to accept all requests on special autonomous area, they will be in charge of, in a link of structural reform as governmental policy. Although one of the requests is the special autonomous area which any enterprise can supply electricity, even in a case who are not electric utility companies or PPS, and it is proposed from plural local government, METI intends to correspond this request within a frame of the current Electricity Enterprises Act. Deregulation for safety distance for hydrogen station regulated by High Pressure Gas Safety Act and also domestic fuel cell both can be solved by special autonomous area concept.

3.Development of SOFC
(1) Tokyo Gas Co., Ltd.
Tokyo Gas has developed SOFC which can be started up within 3 ` 4 hours, less than one-third in comparison with start up time required for conventional SOFC. Ceramics are generally used not only for electrolyte but also electrodes, which might cause cracks due to thermal expansion, so components made of metal are expected. Adopting zirconia as base material for electrolyte, and nickel oxide and zirconia for anode and alloy based on ferrite for cathode, the company lowered operating temperature by 200 ` 300 from conventional 1000. Tokyo Gas plans to build 1 kW stack consisted of 80 fuel cells and start demonstration test in 2004. The ultimate goal of the company is to lower manufacturing cost down to 100,000 yen per kW for commercialization.

(2) Hosokawa Powder Engineering Research Institute
Hosokawa Powder Engineering Research Institute (Hirakata City) has developed novel electrode for SOFC with operating temperature at 700, in cooperation with Joining and Welding Research Institute, Osaka University. The electrode is made of compound particles bonded between nickel oxide particles (500nm average diameter) and zirconia particles (100nm average diameter) by special technology owned by Hosokawa without using any binder. They conducted power generation test using the electrodes and confirmed superior performance on power density.

(3) Japan Fine Ceramics Center (JFCC)
JFCC has developed nano-ceramics film which is used as SOFC cathode for high temperature operation, in cooperation with NGK SPARK PLUG CO., LTD. The cathode with special crystal structure is made, using high power and fine controlled EBEPVD(Electron Beam-Physical Vapor Deposition) facility owned by JFCC.
That is, Lanthanum-Strontium-Manganese-Oxide is formed as thin column shape crystal structure and more over each one has feather shape structure. Column shape crystal structure improves heat-resistant characteristics. Feather shape structure not only relaxes stress from thermal expansion differences but also restrains interface reactions which improves exfoliation-proof. So they said that both of life elongation and higher power generating efficiency are expected and also has merit to increase area for gas-ionization due to feather shape structure.

The project team is under the direct control of the president and 20 ` 30 members have been working on the development of SOFC. The company accelerates to complete the test model by December 2003, and plans to commercialize it at the beginning of the 2005, after one year operation test although they are in a stage now to assemble a test module. The company has spent 500 million yen a year except personnel expenses, which might be expanded further depending on the situations from now and has intention to raise FC as new energy business. The company also aims to lower operating temperature and improve life time by using its own unique ceramics.

4.Development of PEFC and DMFC
Ube Industries, Ltd. Toagosei Co., Ltd. and Takeo Ymaguchi, associate professor of Tokyo University have jointly developed a stronger material for electrolyte membrane of PEFC. The team made the electrolyte membrane by making many fine holes on a chemical resistant resin film and filling some polymer into the small holes. Existing membranes cannot be used for long time because they swell by penetration and reduce power generation capability when methanol is introduced in the cell. Membranes made from new material are expected to overcome these problems. The team confirmed that generation capacity of the fuel cell made by new membranes has not been deteriorated for a five months test run. In addition, power density was 1 Watt/cm2 when hydrogen is directly fed as fuel. The fuel cell is also expected as DMFC for PDA. The two companies will start shipping samples in March 2003.

6.Development of New Type FC
The Central Research Institute for Electric Power Industries (CRIEPI) will begin the real development of intermediate temperature range fuel cell, which operable temperature range is 250~500 . They confirmed that the eutectic salt of potassium hydrogensulfate and sodium hydrogensulfate, adopted as electrolyte, is stable in the temperature range from 100 to 500 and has high proton conductivity of more than 0.1 S in wet oxidation and reduction conditions. This molten hydrogensulfate has been confirmed not to be active to the candidate structural materials for fuel cell, such as platinum, gold, carbon and aluminum, thus they have prospect to be able to assemble the intermediate temperature type FC with combination of these materials. They aim to tackle on the evaluation tests of power generation using the prototype fuel cell in 2003.

The research group of Professor Ichikawa and et al, Catalysis Chemistry Research Center of Hokkaido University, developed the technology which can easily store the hydrogen generated by water electrolysis. Although Professor Ichikawa had already developed organic hydride which is clear fluid formed by chemical reaction of hydrogen, and the newly developed technology is the process to generate electric power by direct reaction of sprayed hydride with oxygen, and also process to store hydrogen generated by water electrolysis as hydride formed again by the generated hydrogen. The process does not require the device to take out the hydrogen and can make system compact and replenishment of hydride is not required.
