PURPOSE:To provide a metal hydride container which is small in size and simple in structure by a method wherein the container is provided with a heat exchanger having thermal medium passage surrounding a heat pipe and circulating therein. CONSTITUTION:A helical grooved medium passage 34 having a substantial semi- circular section is arranged at the inner circumferential surface of a heat exchanger 36 of ring-shaped block and both ends thereof are connected to a thermal medium flowing port 35b and a flowing-out port 35a. When the thermal accumulation is to be performed, a thermal energy is transmitted from the thermal medium circulating in the thermal medium passage 34 to a heat pipe of sleeve form to heat the metal hydride 26, the generated hydrogen gas is passed through a porous cylindrical body 29 with a bottom capable of passing hydrogen but not metal hydride, passed through the valve 27 and then guided into a hydrogen cylinder through a pipe 28. In case of a thermal radiation, the hydrogen gas passed through the valve 27 and the pipe 28 is passed through the porous partition body 29, and the heat which is generated under a contact with the metal hydride and reacted with it is transmitted to the thermal medium of the heat exchanger 36. |
