Abstract:
1. A fuel cell system comprising: a fuel cell that generates electric power by electrochemically reacting a reactant gas mixture; a reactant gas supply unit configured to supply a reactant gas; a gas circulation unit configured to mix a circulating reactant gas from the fuel cell with the reactant gas to supply the reactant gas mixture to the fuel cell; a temperature control unit having a cooling flow path through the fuel cell, a circulating pump configured to circulate a heat transfer medium through the fuel cell, and a radiator on the cooling flow path to adjust the temperature of the heat transfer medium; a gas temperature-detecting unit configured to detect an inlet reactant gas mixture temperature of the reactant gas mixture before the reactant gas mixture enters the fuel cell; a heat exchange unit in the fuel cell through which an outlet side of the reactant gas mixture and an inlet side of the heat transfer medium flows, the heat exchange unit configured to perform heat exchange between the reactant gas mixture and a portion of the heat transfer medium; and a control unit programmed to:
