1.Policies by National Government
(1) Ministry of Environment
@Ministry of Environment decided to introduce a set of hydrogen fueled 2 kW output PEFC into the ministry as a trial operation. The lease rate of the PEFC is 300,000 yen/month and the generation cost is about 700 yen/kWh. Because hydrogen is supplied directly from a hydrogen cylinder, construction for installation is unnecessary and exhausted heat is little. The Denki Shimbun (electricity) and The Chemical Daily Aug. 23, 2005.

(2) Ministry of Economy, Trade and Industries
@Ministry of Economy, Trade and Industries decided to establish gAdvanced Hydrogen Science and Technology Research Centerh (tentative) by gathering about 40 top experts from Japan and overseas, and it will make research on fundamental mechanism of hydrogen embrittlement for 7 years since 2006 fiscal year. In addition to materials industries, such as steel, aluminum, nonferrous metals etc., participation of users like automobile makers is solicited, and the project will be promoted by collaboration among industries, government and academic sector. Development of highly durable new alloys is expected by elucidating mechanism of hydrogen embrittlement. The Chemical Daily Sept. 7, 2005.
@The ministry and gOsaka FCV Promotion Congressh will hold a technological conference and a trade fair named gEXPO Seminar in Osakah on Nov. 29 and 30, 2005 in Osaka International Convention Center. It is in a series of activity of gPublicity for Strategic Promotion of FC Introductionh by the ministry. The Nikkan Kogyo Shimbun (business and technology) Sept. 7, 2005.
@In order to speed up cost reduction of home-use PEFC, the ministry recently solidified to release specification of PEFC auxiliary components of 5 companies, Ebara Ballard Corp., Sanyo Electric Co., Ltd., Toshiba FC Systems Corp., Fuji Electric Advanced Technology Co., Ltd. and Matsushita Electric Industrial Co., Ltd. Because half of the cost of PEFC systems is those of auxiliary components, such as pumps and blowers, the ministry concluded that the development should be promoted by releasing the specifications as well as by using common components in order to commercialize the systems of price below 1 million yen/set. Concretely, the release will be made without the name of company considering confidential matters of the companies, and the ministry is also examining the range of the common components for releasing the specifications. The Chemical Daily Sept. 16, 2005.
2.PAFC Business Deployment
@Anticipating new large scale market of PAFC, such as future power sources for hospitals and small scale hydrogen station, Fuji Electric Advanced Technology Co., Ltd. decided policy to grow up PAFC business to 10 billion yen business. The company considers that sales for hospitals should be strengthened since the next fiscal year, taking account of amendment of the fire fighting law, while it should match other competitive power sources by further cost reduction. Moreover the company aimed at future infrastructure of hydrogen. If the company develops a system in which town gas can be instantaneously switched to LP gas, an advantage that the system can be used usually as well as in emergency is a sales point to hospitals. For hydrogen infrastructure, hydrogen can be produced by operating only the reformer in the night, when the electric load becomes low. Recently the market of PAFC is becoming wide for instance in sewage disposal facilities etc. The exhausted heat can be used for incubation of bacteria and it can also be used in absorption refrigerator for air conditioning. Thus PAFC has characteristics for a widely applicable dispersed power system. It should also be pointed out that PAFC is a power source in RPS (special measure law for utilization of new energy etc.). The Chemical Daily Sept. 16, 2005.
3.Development and Business Deployment of SOFC
@Nippon Shokubai Co., Ltd. introduced a large-scale production facility producing electrolyte sheets for SOFC in its Himeji factory and enlarged production scale from 100,000 sheets annually to 1 million sheets (5 inch size) annually. Because inquiries are increasing mainly from oversea FC makers and future demand increase is anticipated in the domestic market, the company decided to promote market exploitation by establishing mass production facility. The company is also developing SOFC cells and the company intends to cultivate new business from electrolyte to cell. The company developed thin zirconia sheets by its own powder handling technology and ceramic sintering technology, and it supplied zirconia sheets to a Swiss company, Sulzer Hexis (SH) since 2001. SH produces home-use 1 kW SOFC systems and installed over 100 sets mainly in Europe. In cooperation with Toho Gas Co., Ltd., it started R&D of SOFC cells with the electrolyte technology as core. Though the electrolytes show the same strength as conventional electrolyte materials, excellent ion conductivity is observed in the temperature range from 800oC to 900oC. It is forecasted that small SOFC is propagated in home use and business use from 2008 to 2010, and early commercialization is intended in accordance with this forecast. The Chemical Daily Aug. 24, 2005.
4.R&D of PEFC Elementary Technology
(1) Osaka Gas Co., Ltd.
@In August Osaka Gas Co., Ltd. achieved total 40,000 hour electric power generation in long term PEFC small single cell test started in 1998. The company stated that by this achievement they could accumulate knowledge on conditions for long endurance and aging factors. MEA of 40,000 hour endurance is that made 5 years before, and MEA improved later are now under the operating test. The final goal is aimed at over 90,000 hours. The Nikkan Kogyo Shimbun (business and technology) Aug. 26, 2005.

(2) Asahi Kasei Corp.
@Asahi Kasei Corp. has developed new fluorocarbon polymer electrolyte for PEFC. By reconsidering structure from molecular level, it succeeded in optimization of structure in proximity of sulfonic acid group and also in large improvement of thermal stability and mechanical characteristics in high temperature. Especially the onset temperature of thermal decomposition became 393 and it is 76 higher than that of conventional one. Thermal stability of fluorocarbon sulfonic acid polymer depends on structure where sulfonic acid group attached, and it was found that the thermal stability is remarkably improved by increasing number of CF2 units to 4 or more from conventional 2 repeating units. By adopting short side chain structure, the mechanical characteristics (the glass transition temperature) are improved, while proton conductivity is increased by increasing exchange group density. Thus they examined synthetic method for the 4 or more CF2 units and the short side chain structure without long connecting chain, and they developed highly economic production technology. By these improvements the glass transition temperature became 144 by increase of 19 and the proton conductivity increased from 0.1 S/cm2 to 0.14 S/cm2.
