PURPOSE:To increase the conversion efficiency of fuel gas generated in fuel processing equipment into electric power and to effectively follow quick load variation by incorporating hydrogen storage equipment utilizing a hydrogen storage alloy in a fuel cell power generating system. CONSTITUTION:Hydrogen storage equipment utilizing a hydrogen storage alloy is incorporated in a fuel cell power generating system. unreacted gas of fuel gas generated in fuel processing equipment 3 and supplied to a negative gas chamber and excess fuel gas bypassing the fuel cell are converted into pure hydrogen and the hydrogen is absorbed and stored in a hydrogen storage alloy. The hydrogen released from hydrogen storage alloy is supplied to the fuel cell. The surplus or lack of fuel gas attendant on load variation is compensated by absorption into or desorbed from the hydrogen storage alloy. The fuel cell can cope with quick load increase, and since the unreacted gas in exhaust fuel gas can be converted into electric power, the gas produced in the fuel processing equipment 3 is almost completely utilized. Thereby, the load response capability and fuel efficiency of the power generating system are increased. |
