Claim 0:
1. Fuel cell system comprising:
fuel cell having cathode and anode;
a turbocharger having a turbine to which exhaust fuel gas and exhaust oxidizing gas discharged from the fuel cell are supplied as combustion gas and having a compressor driven by the turbine;
oxidizing gas supply line for supplying oxidizing gas compressed by the compressor to the cathode;
a heat exchanger that heats the oxidizing gas in the oxidizing gas supply line by exhaust gas discharged from the turbine and that flows the exhaust gas to combustion exhaust gas line;
bypass line having one end connected to upstream side of the heat exchanger in the oxidizing gas supply line and bypassing the oxidizing gas;
a flow regulation valve provided on the bypass line; and
a control unit including a processor and a memory storing a program that is executed by the processor and that causes the processor to execute a function, wherein
the function includes control of the flow regulation valve based on ambient air temperature to control bypass flow rate of the oxidizing gas,
the other end of the bypass line is connected to downstream side of the heat exchanger in the combustion exhaust gas line, and
the function further includes control of the flow regulation valve based on the ambient air temperature to regulate flow rate of the combustion gas supplied to the turbine.
