1. Governmental Policy and Activity
(1) Ministry of Economy, Trade and Industry
Ministry of Economy, Trade and Industry will start a project to support small-to-medium sized enterprises to be able to take part in developments of fuel cell. They intend to make a concrete list of parts and processing technologies which fuel cell manufacturers need and support the small-to-medium sized enterprises having the above technologies for the manufacturing and back up them to realize the cooperative development and receive the order concerning fuel cell. Further, they promote to exchange information between the enterprises and foreign manufacturers. They will make a list until March, 2005 as the first step, showing the concrete specifications about the parts which fuel cell manufacturers need, such as water pump, electromagnetic valve, flow control valve and various sensors and distribute the lists to small-to-medium sized enterprises and collect the enterprises who want to challenge positively.

2. Activities on International Standardization
The Japan Electrical Manufacturesf Association (JEMA) places great importance on activities concerning international standards for micro fuel cell used for mobile information appliance. JEMA strengthens their activities to reflect Japanese opinions and proposals to the international standards as they have been entrusted a research project from Ministry of Economy, Trade and Industry and NEDO. The international standards on FC have been discussed in TC105 of IEC and its Working Group (WG). Although WG for micro FC did not exist, it has been admitted that micro FC might be separated from WG-7 (portable FC) in 2003, by a strong request from Japan. Succeeding this, working group WG-8 (safety), WG-9 (performance) and WG-10 (interchangeability) have been established successively. WG-10 was to take the chair by Japan. The fifth plenary session, IEC/TC105, was held in Tokyo in June, 2004.

6. Research and Development of Elemental Technology for PEMFC
(1) Technology Research Institute of Osaka Prefecture (TRI Osaka)
H. Minami, Chief Researcher and his group, Machinery and Metal Department, TRI Osaka developed a technology processing precisely and effectively hard metal (super hard alloy) which is difficult to machine, by utilizing electric discharge from electrode made of zinc alloy. Paying attention for high speed electric discharge characteristics which zinc alloy has, it is applied a precise processing technology for stainless steel. It is expected to be applied for development of separator for PEMFC from now.
If cupper mesh electrode having 0.18 mm square holes is put between hard metal and zinc alloy and electric discharge is applied, many fine rectangular poles are formed by zinc alloy passed through the mesh. The zinc alloy becomes electrode if applied reverse discharge and it can make fine holes on the object. Forming zinc alloy electrode repeatedly, they succeeded to make fifty fine holes (0.25 mm – 0.3 mm) on hard metal of 1 mm thickness for 70 minutes. And they confirmed that they can form fine flow passage (width and depth are both about 70 m) on the hard metal.

(2) The National Institute of Advanced Industrial Science and Technology (AIST)
AIST developed a mass production technology with high purity and high quality single layer carbon nano tube at low cost, around 1/500 in comparison with conventional technology. The developed technology is a kind of CVD (Chemical Vapor Deposition). Thin membrane consisted of iron fine particles is formed on a base plate as catalyst and reacts with ethylene gas at 750, atmospheric pressure and make single layer carbon nano tubes grow from the base plate. The nano tube became 2.5 mm for about 10 minutes according to the experiment. This growing speed is 3,000 times in comparison with conventional technology. This single layer nano tubes have the uniformity in direction and the diameter is 1nm. Soot formation is completely suppressed by adding extremely small amount of water for reaction. The purity is 99.98% or higher and the purity is 2,000 times higher than conventional method. The fruits will be published on gScienceh, science magazine in USA and the samples would be available soon.

(3) Liquefied Petroleum Gas Center
Liquefied Petroleum Gas Center judged that commercialization targets for desulfurization and reforming catalysts most suitable for LPG have been attained through the elemental technologies developments for LPG fueled PEMFC system developed for 5 years started from 2001. They confirmed longer than 4,000 hours desulfurization performance of combined agent between metal and zeolite. They developed steam reforming catalyst of Ru type which initial activity and durability is superior to conventional Ru catalyst on market, being considered many start and stop operation and anticipated that nearly 30 thousand hours life would be expected from the comparison test. In this technology development, they aim that the desulfurization catalyst keeps performance more than 1 year, which sulfur content in LPG after desulfurization is less than 50 ppm, and the reforming catalyst keeps the performance for more than 5 years, which reforming process efficiency is 75% under S/C less than 3. Small scale home use FC tends that sulfur concentration is increased according to the increased gas consumption as LPG is supplied with natural evaporation method, so development with high performance catalyst has been requested.
