    摘要： Molded bodies of a hydrogen absorbing alloy accommodated in a hydrogen storage container are made readily replaceable to ensure stabilized supply of hydrogen gas. When exhibiting an impaired hydrogen absorbing-desorbing capacity, the molded bodies can be easily replaced by new molded bodies, whereby a specified hydrogen absorbing-desorbing capacity can be maintained. The hydrogen gas released from the storage container is partly utilized to heat the container and thereby maintain the alloy at a predetermined temperature, consequently assuring a device, such as a fuel cell, of stabilized supply of hydrogen from the container.
