摘要： A fuel cell system includes a fuel cell, an operation controller and an air-conditioning mechanism. In response to a heating request for the air-conditioning mechanism during ordinary operation where the fuel cell is operated at an operating point on a current-voltage characteristic curve of the fuel cell, the operation controller compares a heat value-based required current value with an output-based required current value. When the output-based required current value is equal to or greater than the heat value-based required current value, the operation controller causes the fuel cell to be operated at an operating point on the current-voltage characteristic curve. When the output-based required current value is smaller than the heat value-based required current value, the operation controller controls the operating point of the fuel cell to an operating point of lower power generation efficiency than that of the operating point on the current-voltage characteristic curve.

摘要： A fuel cell system includes a fuel cell, an operation controller and an air-conditioning mechanism. In response to a heating request for the air-conditioning mechanism during ordinary operation where the fuel cell is operated at an operating point on a current-voltage characteristic curve of the fuel cell, the operation controller compares a heat value-based required current value that is a current value of an operating point that is located on the current-voltage characteristic curve and satisfies a required heat value for the fuel cell with an output-based required current value that is a current value of an operating point that is located on the current-voltage characteristic curve and satisfies a required output for the fuel cell. When the output-based required current value is equal to or greater than the heat value-based required current value, the operation controller causes the fuel cell to be operated at an operating point on the current-voltage characteristic curve. When the output-based required current value is smaller than the heat value-based required current value, the operation controller controls the operating point of the fuel cell to an operating point of lower power generation efficiency than that of the operating point on the current-voltage characteristic curve.

摘要： When starting operation of a fuel cell below the freezing point, a fuel cell system adjusts the open degree of a hydrogen pressure adjusting valve, introduces hydrogen to a hydrogen entrance of the fuel cell so as to make the total pressure of the hydrogen entrance is a first pressure, and starts a hydrogen circulation pump. If at least one of the cell voltages acquired by a cell voltmeter is below a predetermined voltage, the system determines that clogging is caused in a hydrogen flow channel in the fuel cell. When it is determined that clogging is present, the open degree of the pressure adjusting valve is adjusted and hydrogen is introduced to the hydrogen entrance so that the total pressure of the hydrogen entrance is a second pressure which is higher than the first pressure. Then, the hydrogen circulation pump is stopped and the fuel cell is warmed up to dissolve the clogging of the hydrogen flow channel. Thus, it is possible to suppress degradation of the fuel cell upon an operation start below the freezing point.
