PROBLEM TO BE SOLVED: To provide a fuel cell system in which a sure cooling of the fuel cell for transient increase of heat in a high output of the fuel cell. SOLUTION: This has the fuel cell 1 wherein an electric power is obtained by the chemical reaction of hydrogen and oxygen and the first heating medium circulating in the fuel cell 1, and installed with a path 10 for the main cooling having a radiator (cooling means) 11 to discharge to the outside of the system the heat generated in the fuel cell 1, and a path 20 for an auxiliary cooling having the second heating medium that has a lower temperature than that of the first heating medium, and corresponding to the output of the fuel cell 1, the second heat medium is made to flow into the path 10, and the first heating medium and the second heating medium are mixed and made to circulate in the fuel cell 1. |
