| Abstract | We have developed a high pressure hydrogen regulator for fuel cell vehicles which achieves an improved pressure regulation characteristic, higher reliability, and a lighter weight than the conventional regulator. The pressure regulation characteristic was improved by reducing sliding friction of the seal around the periphery of the piston. Reliability was achieved by decreasing wear through the improvement of surface roughness of the parts which repeatedly open/close and slide during operation. Furthermore, we have achieved weight saving by abolishing stainless steel components of the sliding parts and applying aluminum alloy components with a surface treatment. |
