Abstract
A hydrogen storage tank () and method for replacing an open-close valve that prevents oxidizing of a hydrogen absorption alloy (MH) accommodated in a tank body () when replacing an open-close valve () connected to a hydrogen supply-release pipe () extending from a tank body (). The hydrogen storage tank () includes a tank body () accommodating hydrogen absorption material (MH), a hydrogen supply-release pipe () for supplying hydrogen gas to the tank body () and releasing hydrogen gas from the tank body (), and a gas supply pipe () for supply inert gas to the tank body () and arranged independently from the hydrogen supply-release pipe (). The method for replacing an open-close valve () connected to the hydrogen supply-release pipe () includes supplying inert gas through a gas supply pipe () to the tank body () and replacing the open-close valve in a state in which inert gas can be released from the hydrogen supply-release pipe ().
