(2) Tokyo Metropolitan University
Prof. Kanemura and his group in the above university have succeeded in making electrode catalyst layer by electrophoresis. It is a method in which colloidal catalyst particles dispersed in solvent are deposited on electrolyte membranes by electric field. Thickness and composition of the catalyst layer can be controlled by changing electrophoresis conditions and composition. The electro-catalyst layers of high uniformity in the porosity can be made compared with electrode made by conventional hot press. By experiment using MEA made by this method, more than twice maximum electric current was observed in comparison with those by hot press. For making this MEA, nafion membrane was sandwiched in the central part of an electrophoresis cell and electrophoresis was made by direct current power source. In the solution for the anode side platinum loaded carbon was dispersed in perchloric acid aqueous solution. The thus made electrodes were observed with an electron-microscope, and it was confirmed that catalyst layers of very high uniformity were observed. [The Chemical Daily Sept. 11, 2007]

7. Technology Development for Hydrogen Formation and Purification
(1) Sharp Corp. and Research Institute of Innovative Technology for the Earth (RITE)
In collaboration with RITE, Sharp Corp. succeeded in research of hydrogen formation from mixed saccharides (glucose) produced from cellulose bio-mass. The yield was half of theoretical yield (4 mole of hydrogen / mole of saccharides.) The rate of hydrogen formation was confirmed and it was 20 L/h with 200 g of bacteria (colon bacillus) in a reactor of 1 L capacity. The colon bacillus used in this research is a bacteria originally created by gene manipulating technology. Saccharides was poured into the reactor containing the bacteria and hydrogen was formed at the above rate. Hereafter research will be done to increase the yield, while long continuous operation will also be tried aiming at real production of bio-mass hydrogen.

(2) Tohoku University etc.
A research group of Prof. Ishida, a professor in graduate school of Tohoku University, Dr. Takahisa of Organization for Promotion of Science and Technology etc. set forth on Sept. 6, 2007 that they developed aluminum alloy, which forms hydrogen by pouring water. The research group added inexpensive element to aluminum and made its crystals of uniform size of several micron m by heat treatment. When the alloy is reacted with water, hydrogen is formed and aluminum is oxidized to aluminum hydroxide. It is a characteristic point that the reaction proceeds at a relatively high rate even at the room temperature, and 1 L hydrogen was formed from 1 g aluminum. It seems that by controlling crystalline texture influence of surface aluminum oxide film, which prohibits the reaction, is suppressed. Hydrogen can be formed at low cost.

(3) Waseda University
Prof. Kikuchi, Prof. Matsukata et al. in Waseda University discovered active catalyst for accelerating shift reaction of CO and water vapor to form hydrogen, and it does not need pre-treatment. It retards poisonous effect of CO to platinum catalyst and brings high hydrogen formation ratio. It is perovskite type oxide and it is a catalyst of platinum and palladium loaded lanthanum cobalt oxide. The catalyst contains 1% platinum and 0.5% palladium. Perovskite oxides have high oxide ion conductivity and a property of easily releasing lattice oxygen, which seems to enhance oxidation-reduction reaction. Platinum and palladium are added to activate the reaction at low temperature. By using this catalyst the shift reaction was made. Higher CO conversion efficiency was obtained than conventional catalyst in experiments, while the activity was stable. Activity was almost not observed for the perovskite without platinum and palladium, and platinum or palladium on silicon shows no activity, so that it can be concluded that high activity is brought us by synergy effect of these three components. [The Chemical Daily Sept. 14, 2007]
(4) Tokyo Institute of Technology
Prof. Watanabe, an associate professor of Tokyo Institute of Technology, developed a small equipment for efficiently producing hydrogen from low concentration alcohol, like beer. From 1 can of beer (350 cc) enough hydrogen for FCV to run about 2 km is obtained. By heating alcohol at high temperature by direct current discharge, alcohol decomposes to atomic level, e.g., hydrogen, carbon and oxygen, and by cooling it and separating hydrogen gas from it, hydrogen can be obtained. The cost is relatively high, but it is an advantage that low purity alcohol unnecessary in alcohol related factories can be used, Prof. Watanabe said.

8.Development and Business Deployment of Hydrogen Storage and Transport Equipments
Chugoku Kogyo Co., Ltd. will advance to business of hydrogen fuel tanks for automobiles in earliest case in March of 2009. The company is now developing super-high-pressure hydrogen tanks in collaboration with Prof. Okamoto of Hiroshima University, and the company aims at sales for FCV and cars with hydrogen RE engines. The tank under development is made as follows; the inner container of cocoon shape is made by molding of plastics as a unit and then epoxide resin impregnated carbon fiber reinforced plastics (CFRP) is wounded on the inner container. It is light-weight but its strength is as high as those of aluminum and stainless steel. Structure of the inner container is multiple layers of specific resin, so that hydrogen leakage is little. The future tasks are to secure the strength of hemispherical parts by changing CFRP wounding and to develop mouthpiece structure of less hydrogen leakage.

9. Development of New Types FC like Bio-cells
On Aug. 21, 2007 Sony Corp. announced that the company developed bio-electochemical cells, which generate electric power using glucose as energy source. They do not emit greenhouse effect gases like CO2. When 4 cells were connected in series and 7 cc of glucose is charged to each cell, portable music player, "Walkman" worked for several hours. In principle glucose is decomposed by varieties of enzymes to generate electric power. When glucose is decomposed, electrons and hydrogen ions are generated on the negative electrode. Hydrogen ions migrate to the positive electrode through a separator (insulating sheet), and on the positive electrode hydrogen ions form water by reaction with oxygen in air. Small amount of water formed is evaporated to air, and others are absorbed in the positive electrode of porous carbon. The generated power of this cell is 50 mW per cell. They intend to improve the generating performance and endurance. [The Sankei Shimbun, The Nikkei Sangyo Shimbun (economy and industry) and The Fuji Sankei Business Eye Aug 24, 2007]
