HYDROGEN STORAGE TANK AND REPLACEMENT METHOD FOR ON-OFF VALVE |
摘要 |
A hydrogen storage tank (11) and method for replacing an open-close valve that prevents oxidizing of a hydrogen absorption alloy (MH) accommodated in a tank body (12) when replacing an open-close valve (30) connected to a hydrogen supply-release pipe (28) extending from a tank body (12). The hydrogen storage tank (11) includes a tank body (12) accommodating hydrogen absorption material (MH), a hydrogen supply-release pipe (28) for supplying hydrogen gas to the tank body (12) and releasing hydrogen gas from the tank body (12), and a gas supply pipe (24) for supply inert gas to the tank body (12) and arranged independently from the hydrogen supply-release pipe (28). The method for replacing an open-close valve (30) connected to the hydrogen supply-release pipe (28) includes supplying inert gas through a gas supply pipe (24) to the tank body (12) and replacing the open-close valve in a state in which inert gas can be released from the hydrogen supply-release pipe (28). |
