| 摘要 |
The present invention provides a fuel cell power generating system comprising a hydrogen generator (1) which generates hydrogen gas by allowing a source material to undergo a reforming reaction and a fuel cell (3) which is equipped with a fuel electrode and an air electrode and which generates electric power by allowing the hydrogen gas supplied to the fuel electrode and oxygen gas supplied to the air electrode to react electrochemically with each other. The fuel cell power generating system further comprises a water recovering portion (5) configured to recover water from water vapor discharged from at least one of the fuel and air electrodes, a water storing portion (6) which is equipped with a tank (6a) for storing water recovered by the water recovering portion (5), and a water supply portion (10) configured to supply water stored in the tank (6a) to the hydrogen generator (1), wherein the tank (6a) is configured, in order to prevent water stored in the tank (6a) from decaying, such that the stored water is dischargable to the outside, and wherein the fuel cell power generating system is so configured as to make a decision on whether or not to discharge the stored water to the outside for the prevention of water decay. <IMAGE> |
