    SHOWA DENKO, as a link of fine carbon business chain, plans to have a share in PEFC separator market. Optimizing production process for pressing and heat treatment multi-layered special paper and developing injection molding process which is suitable for mass production, and arranging both technologies , they will cope with the needs of PEFC production for home use and FCV.
    SHOWA DENKO has a excellent experience in PAFC separator. In this case, the process is to graphitize multi-layer special paper after impregnating phenol and press them and this glassy carbon has features that are good in tightness and easy to scale up the size. Applying this process to PEFC separator production, they intend to reduce the cost by optimizing heat treatment temperature for PEFC as the graphitizing is not required for low operating temperature of PEFC. As for injection molding process, there is possibility to improve production efficiency greatly by producing raw material sheet, composite of special graphite fine powder and binder resin, by injection molding process.

(5) Chiba University
    Prof. Katsumi Kaneko, faculty of science, Chiba University, developed nanometer size capsule type platinum fine particle. It is a simple method that, after depositing platinum on surface of nanometer silicon dioxide (silica) particle and then silica is removed by dissolving. The structure is that about 20 nanometer platinum capsules form cluster like a grain of rice with about 1 nanometer clearance. The capsule has holes formed when silica is removed and both inside and outside surface are effective as the result. And total surface area was confirmed that is 4 to 8 times in comparison with normal nanometer size platinum black surface area. Having nanometer size hollows and the surface area is so large as activated carbon, the capsule is expected to be able to utilize as a catalyst which has active and selective reaction characteristic and as the platinum electrode of FC.

    Toshiba has already decided to put the PEFC for PDA on sale around October 2002 and has also determined to make the new FC come to market for book type personal computer. The output of new FC has been brought up over 15W and this is almost twice as much as that of the existing ones.
    The development on PEFC in Toshiba has begun with participating in the NEDO project in 1992 and took notice of DMFC in 1997, which was not required reformer, and manufactured the electrode which put a few nm platinum catalyst on the surface of the carbon particle of 1ƒÊm diameter and was totally coated by platinum-proton catalyst. The DMFC can be operated for several scores of hours with 10 cc of methanol.
    The consumption of 1g of methanol produces 1cc of water. Toshiba said that these small amounts of water can be thoroughly evaporated by a blower. To make PEFC for PDA available on market, Toshiba has tried to change the carbon materials to light plastics and aims to make FC smaller, lighter, and lower in the price. For instance, Toshiba has investigated the possibilities to replace from carbon made separator with plastics having electric conductivity, light and anticorrosive, and also replace from metals with plastics. The high quality electrode, one of the key devices on PEFC, has been applied for the patents

(2) AIST and Mazda Motor Corporation
    Mr. Akiba, chief researcher of AIST(National Institute of Advanced Industrial Science and Technology) and a researcher of Mazda Motor Corporation announced that they succeeded in producing the magnesium-titanium alloy which has excellent hydrogen absorption capability. The characteristic of production method is in the adoption of the mechanical alloying method, with which method metal materials are mechanically mixed, instead of melting method. Hydrogen absorption capacity of magnesium is 7.6% by weight, titanium 4.1%. However, the temperature for the reaction is required higher than 300 Ž and the research has been carried out to decrease this temperature. The new alloy has body-centered cubic structure and crystal structure shows that two hydrogen atoms can be stored in each atom of metal. The alloy can be expected to store hydrogen 5% by weight (It is three times more than that of rare earth alloys) and also to make reaction temperature below 100C. The alloy is considered to be applied not only for hydrogen absorption material but also broad application for light weight structure materials of cars.
