Abstract
This paper describes achievements in fiscal 1977 of patent information surveys on hydrogen technologies. Japan is most enthusiastic in developing the thermo-chemical hydrogen manufacturing method. While no noticeable patents were found on the electrolytic method, researches on membranes and electrodes are expected. With regard safety assurance, it is necessary to establish safety assuring technologies suitable for each stage of hydrogen manufacture according the flow of manufacturing, liquefaction, storage, transportation and utilization of hydrogen. Development of mechanisms to prevent hydrogen embrittlement and destruction (leakage) is especially demanded. Enhancement of economic performance and reliability of hydrogen fuel cells requires research and development in the whole fuel cell configuration and also in the fields of auxiliary devices, in addition to that for catalysts and electrodes. Few patents are applied for in solid electrolyte and molten salt fuel cells. The most noticeable problems in hydrogen combustion devices are prevention of reverse ignition, safety measures for colorless flame, and positive utilization of hydrogen combustion characteristics in mixed combustion. Inventions tackling squarely with these problems can hardly be found. It was difficult to discover contributive and effective technologies because the hydrogen combustion characteristics are widely different from those of other fuels. (NEDO)
