摘要： A fuel cell system capable of estimating fuel gas concentration and/or impurity gas concentration, with a simple configuration, is provided. The fuel cell system has an anode path composed of a supply path 75 for supplying fuel to the anode electrode in a fuel cell stack 20 and a discharge path 76 for discharging the fuel from the anode electrode in the fuel cell stack 20. The fuel gas concentration or impurity gas concentration in the anode path is derived based on the pressure loss in the anode path. The pressure loss can be measured by means of a differential pressure gauge 58 or pressure meter disposed in a piping, thus gas concentration can be estimated with a simple configuration without requiring any special measuring instrument.

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.

A bypass valve is arranged between an oxidation gas supply path and a cathode-off gas channel. In a state in which supply of an oxidation gas to a cathode falls short, pumping hydrogen is included in a cathode-off gas. Therefore, a valve open degree of the bypass valve is regulated, and a flow rate of bypass air is regulated to control the exhaust hydrogen concentration.

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： An object of the present invention is to provide a fuel cell system capable of raising the temperature of a discharge valve and restraining the discharge valve from freezing by a simple structure. The fuel cell system has a circulation system for circulating hydrogen off gas, which is discharged from a fuel cell, to the fuel cell, an exhaust/drain valve for discharging a fluid passing through the circulation system to the outside, and a refrigerant flow path through which a refrigerant, which is circulated to the fuel cell, flows. The exhaust/drain valve has a valve body provided with a flow path which interconnects the interior of the circulation system and the outside. A part of the refrigerant flow path is provided by penetrating the valve body so as to be independent of the flow path.
