| 抄録（英） | This article describes the evolution of the high-pressure hydrogen storage system parts developed for new fuel cell vehicles (FCVs) with the aim of helping to further popularize FCVs. New high-pressure hydrogen tanks with three different lengths were developed to store the necessary amount of hydrogen in the system without sacrificing the interior space of the sedan-type vehicle. Mass-production capabilities were increased and major cost savings were achieved by adopting new machining methods for the high-pressure valves. Assuming that the system might be refueled at a wide range of refueling stations in the future, a crank-shaped flow path was adopted in the solenoid valve to discourage the inflow of water, and notches were added on the moving sliding parts of the solenoid valve in six locations to reduce the adhesive force between the walls and the moving part in freezing temperatures. The structure of the piston was also simplified from three to two layers by enabling direct sliding with the regulator body by improving machining method. As a result, high-pressure regulator costs and weight were reduced. The same high filling efficiency as the previous system was maintained despite the adoption of three tanks with significantly different volumes by measures such as optimizing the hydrogen injection angle inside the tank. In addition, the developed tanks and valves obtained certification under United Nations Regulation 134 (UN-R134), which was established to allow mutual recognition of FCVs and other vehicles. 翻訳 |
