The present invention provides a fuel cells-based generator system that prevents a catalyst in fuel cells from being poisoned and a potential on oxygen electrodes of the fuel cells from lowering, while improving the energy efficiency. While I2 is fed from a halogen tank 41 to a preliminary reaction tank 30 via a first conduit 33, H2O is fed from a water tank 43 to the preliminary reaction tank 30 via a second conduit 34. The preliminary reaction tank 30 is heated by the heat transmitted from a stack of fuel cells FC, and the reaction expressed as H2O + I2 -> 2HI + (1/2)O2 occurs in the preliminary reaction tank 30. HI produced by the above reaction is dissolved in excess H2O and fed into a reaction tank 50 via a fourth conduit 36. The reaction tank 50 is heated by the heat transmitted from the stack of fuel cells FC, and the reaction expressed as 2HI -> H2 + I2 occurs in the reaction tank 50. The gaseous mixture of H2 and I2 is flown into a hydrogen purifier 60 via a sixth conduit 54. The hydrogen purifier 60 separates gaseous hydrogen H2 from the gaseous mixture. The gaseous hydrogen H2 is then fed into flows paths of gaseous hydrogen in the stack of fuel cells FC. <IMAGE> |
