Abstract

This paper describes surveys in fiscal 1979 on patent information related to hydrogen energy. For the hydrogen manufacturing cycle based on the thermo-chemical method, many patents are related to HI decomposition and separation. A number of technologically superior patents were found in the electrolytic method, but those applicable directly to water decomposition development in the Sunshine Project are not many. The number of patents on metal hydrides in relation with hydrogen storage and transportation has shown some increase, but no change in the qualitative aspect. In safety assurance, many proposals were seen relating to earthquakes. Patents on hydrogen fuel cells decreased in number as a whole, while half of the domestic patent applications is for alkaline electrolyte type fuel cells. In contrast in other countries, many patents are related to the second and third generation fuel cells, not to speak of the first generation, indicating that Japan is standing behind. Technologies to use hydrogen engines practically are concentrated on establishment of hydrogen storage and transportation methods and development of systems with high total energy efficiency, which are reflected in patent applications. Combustion device related problems are in NOx emission suppressing technologies and reverse ignition preventing measures, but trend is lacking  More>>
