<P>PROBLEM TO BE SOLVED: To easily and correctly lower pressure in a tank main body when necessary. <P>SOLUTION: This storage tank for hydrogen storage alloy to store for hydrogen storage alloy is provided with a first releaf passage 12 and a second relief passage 14 separately communicating with the inside of the tank main body 1. On the first relief passage 12, a pressure-sensitive first relief valve 11 is provided to be opened by pressure rise in the tank main body 1 to let pressure in the tank main body 1 off toward the external. On the second relief passage 14, a temperature sensitive type second relief valve 13 is provided to be opened by rise of atmospheric temperature to let pressure in the tank main body 1 off toward the external. <P>COPYRIGHT: (C)2004,JPO |
