Abstract
A fuel cell provided with a reforming catalyst is located in a high-temperature portion on the anode side to cool the high-temperature portion by means of heat absorption of reforming reaction, or a combustion catalyst is provided in a low-temperature portion on the anode side to heat the low-temperature portion by means of heat generation of combustion reaction, or both of the catalysts are provided, by which the occurrence of variations in temperature in a cell reaction region of anode is prevented.
