The fuel cell 51 is a well-known solid polymer membrane fuel cell (PEMFC) in which a large number of unit cells (unit cells) are stacked. Hydrogen gas is supplied to the anode side as a fuel gas, and oxidant gas is supplied to the cathode side. By supplying oxygen-containing air as described above, electric power is generated and water is generated by an electrochemical reaction.

  The hydrogen gas as the fuel gas is supplied from the hydrogen cylinder 52 through the shut-off valve 53 to the fuel cell 51 with a predetermined pressure (in other words, in a predetermined high pressure state), and after being used for power generation, It is introduced into the channel 54. In the hydrogen circulation channel 54, unreacted hydrogen gas is repeatedly supplied to the fuel cell 51 together with fresh hydrogen gas from the hydrogen cylinder 52. Hydrogen gas circulating in the hydrogen circulation channel 54 can be introduced into the dilution box 56 via the purge valve 55.
