<P>PROBLEM TO BE SOLVED: To provide a fuel cell system of good system efficiency. <P>SOLUTION: This system consists of a reformer (1), which generates hydrogen rich reform gas, a fuel cell stack (7), which generates electricity using the reform gas and an oxidizer, a burner (10), which burns the gas discharged from the fuel cell stack, a vaporizer (12), which evaporates the fuel for reforming and water using the heat of the combustion gas from the burner, flow passages (3, 16), which supply the vaporized fuel for reforming and the steam to the reforming machine, and a pressure control equipment (15), which is installed in the middle of this flow ways and makes the pressure in the flow passage of the lower stream of the vaporizer change according to the load change of the above fuel cell stack. <P>COPYRIGHT: (C)2003,JPO |
