<P>PROBLEM TO BE SOLVED: To enable retention of a shape of a heat conduction member even through heat treatment to a hydrogen storage tank housing the heat conduction member. <P>SOLUTION: A plurality of heat conduction members 15 housed in the hydrogen storage tank 11 is each composed of a pair of main parts 16, 17 extending from a center axis L of the hydrogen storage tank 11 in the radial direction, and a connection 18 connecting the pair of the main parts 16, 17 at a circumferential wall side of the hydrogen storage tank 11. The material of the heat conduction member 15 is an aluminum alloy. The connection 18 is in surface contact with the inner circumference surface of a circumference wall 110 of the hydrogen storage tank 11. On the inner surface of the heat conduction member 15, a plurality of shape holding members 20 is fixed with intervals in an axial direction of the center axis L of the hydrogen storage tank 11. The material of the shape holding member 20 is copper. The shape holding member 20 is composed of a pair of flat plates 21, 22 which is surface-joined to the inner surfaces 161, 171 of the main parts 16, 17 and is fixed, and a connection 23 which is surface-joined to the inner surface 181 of the connection 18 and is fixed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
