Claim 0:
1. An SOFC system, comprising a fuel cell module and a cooling system, the cooling system comprising:
a radiator,
a water tank,
a water pump,
a DC step-down transformer configured to step down current produced by the fuel cell module,
a fan configured to cool the fuel cell module,
a condenser configured to cool an anode exhaust gas from the fuel cell module,
a current sensor,
a first flowmeter, and
a second flowmeter,
wherein:
the DC step-down transformer, the fan, and the condenser are connected in parallel, and a solenoid valve group is installed in each parallel supply and is configured to control switching on and off of each supply according to a corresponding signal, to constitute a parallel system, wherein the solenoid valve group comprises a first solenoid valve connected to the DC step-down transformer, a second solenoid valve connected to the fan, and a third solenoid valve connected to the condenser;
the current sensor is provided in a circuit between the fuel cell module and the DC step-down transformer and is configured to detect a current signal of the DC step-down transformer to control the first solenoid valve;
the first flowmeter is provided between the fuel cell module and the fan and is configured to detect a flow signal in a pipeline of the fan to control the second solenoid valve;
the second flowmeter is provided between the fuel cell module and the condenser and is configured to detect a flow signal of anode exhaust gas to control the third solenoid valve;
a first end of the radiator is connected with a first end of the water pump and the water tank, respectively;
a second end of the water pump is connected with a first end of the parallel system; and
a second end of the radiator is connected with a second end of the parallel system.
