    Substantial reduction of greenhouse gas is requested to deal with the global warming issue. As an innovative technique to achieve it, a fuel cell vehicle (FCV) and production, storage and supply technologies of hydrogen, which is fuel of FCV, are the important position in the national policy.

    FCV, which is one of the next generation cars and considered as an ultimate clean energy vehicle, has been developed actively for practical use. Also, demonstration studies of hydrogen refueling stations have been executed including the metropolitan area.

    In this report, it introduces the outline of the JHFC project (Japan Hydrogen & Fuel Cell Demonstration Project), which has been promoted aiming at spread start of FCV and hydrogen refueling stations to the average user in 2015.

    In WG3, the members from automobile manufacturing companies and infrastructure companies discuss about technical issues of the interface between fuel cell vehicle and hydrogen infrastructure. In this paper, the results of the WG3 activities in 2009 are reported. The problems to realize 70MPa full refueling station were examined towards 87.5MPa of maximum refueling pressure. To achieve the full refueling, the introduction of communication refueling was decided. It was observed that ―40℃ pre-cooling is necessary for 70MPa full refueling by simulation. Then, the specifications for 70MPa full refueling station were proposed and reflected to the items in the next project. In addition,th e Japanese version of refueling protocol tests was conducted and the results were reported.

    Several hydrogen refueling stations in the United States and in Germany are reviewed. Recent hydrogen stations tend to refuel hydrogen at the pressure as high as 70MPa and at the temperature as low as -40.degrees centigrade. in order to meet the requirement by the latest fuel cell vehicles. Although the most of the hydrogen stations are in the stage of technical demonstration, discussion about an early market introduction of hydrogen infrastructure are also begun to be investigated.

    Honda has been developing an experimental solar hydrogen station (SHS) in order to propose a solution for energy and global environmental issues. The results from proving tests of the SHS1 suggest that a renewable hydrogen station of a size suitable for household use would require still greater compactness and higher efficiency. Therefore we developed high differential pressure electrolyzer stack, which is an innovative technology. The stack differs from the ordinary high pressure electrolyzer that keeps both the anode side and the cathode side in a high pressure state. Here, instead, the anode side is under normal pressure and only the cathode side is maintained under the high pressure of 35 MPa. Therefore, this one has a simpler structure and can be made compact. Furthermore, the stack here has the functions of both generating and compressing hydrogen. With this stack, SHS2 was made into a compact, highly efficient and low-noise, home-sized hydrogen refueling appliance.

    Hydrogen is attracting attention as a clean fuel that produces no carbon dioxide emissions at the stage of use. However, CO2 is emitted when hydrogen is produced from fossil fuels. Until the day comes when we can supply sufficient amounts of hydrogen from renewable energy sources, hydrogen could be produced from fossil fuels using existing equipment in oil refineries and other factories. In this paper, the author describes the potential hydrogen distribution capacity of industry in Japan. Studies indicate that sufficient amounts of hydrogen could be supplied for the initial stage of a hydrogen energy economy.

    However, this hydrogen must be purified to 99.99% if it is to be used for fuel cell vehicles. When it is purified using current technology, 25-30% of the hydrogen is lost. Thus, new efficient technology for purifying hydrogen is needed.
