ABSTRACT:
A gas compressor and a bypass that bypasses the gas compressor are provided between a hydrogen absorbing tank and a hydrogen gas consumer device such as, for example, a fuel cell. When the hydrogen gas generating pressure is low during an initial period of the hydrogen gas releasing operation of the hydrogen absorbing tank, the gas compressor is operated. When the hydrogen gas generating pressure of the hydrogen absorbing tank becomes sufficiently high due to normalization of the operation of the fuel cell or the like, the gas compressor is stopped, and hydrogen gas is supplied to the fuel cell via the bypass.
