FUEL CELL POWER GENERATION SYSTEM AND OPERATION METHOD THEREFOR

摘要

An aim of the invention is to provide a fuel cell power generation system which can operate in a reduced space to reduce the initial cost and the running cost without deteriorating the performance. In a fuel cell power generation system comprising a fuel cell having an anode, a cathode and a polymer electrolyte membrane, a fuel gas feed pipe for supplying a fuel gas into the anode, an oxidant gas feed pipe for supplying an oxidant gas into the cathode, a reforming unit connected to the fuel gas feed pipe for reforming a raw material gas, a heating unit for heating the reforming unit, a raw material gas supplying unit for supplying the raw material gas into the reforming unit, a water supplying unit for supplying water into the reforming unit, and an air supplying unit for supplying air into the reforming unit, water is introduced into at least one selected from the fuel gas feed pipe, the oxidant gas feed pipe, the cathode and the anode to purge gases retained in the system.
