Patent ID: 10950881

Abstract:
A controller of a fuel cell system executes at least one of a first control and a second control. The first control is executed when a value of current is raised in association with an increase in flow rate ratio of cathode exhaust gas flowing into a bypass, the first control is executed by which the value of the current is raised to boost discharge pressure from a compressor and subsequently, an opening degree of a flow dividing valve is changed so as to increase the flow rate ratio of the cathode exhaust gas flowing into the bypass. The second control is executed when the value of the current is lowered in association with a reduction in the flow rate ratio of the cathode exhaust gas flowing into the bypass, the second control is executed by which the opening degree of the flow dividing valve is changed so as to reduce the flow rate ratio of the cathode exhaust gas flowing into the bypass and subsequently, the value of the current is lowered so as to lower the discharge pressure from the compressor.
