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： There is disclosed a fuel cell system or the like capable of sufficiently reducing an exhaust hydrogen concentration even in a case where a fuel cell is operated in a state of a low power generation efficiency. 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.

摘要： A fuel cell system (1) is provided with a fuel cell (10); a fuel supply system (3) for supplying the fuel cell (10) with a fuel gas; an injector (35) for adjusting a pressure on the upstream side of the fuel supply system (3) and supplying the gas downstream; a control means (4) for controlling the injector (35) to be driven in a prescribed drive cycle. The control means (4) sets the operation status of the injector (35) corresponding to the operation status of the fuel cell (10). The operation status of the injector (opening degree of an injector valve (gas passing area), open time of the injector valve (gas injecting time) and the like) can be set corresponding to the operation status of the fuel cell (electricity generated by the fuel cell (power, current and voltage), fuel cell temperature, abnormal state of the fuel cell system, abnormal state of the fuel cell main body, and the like). Thus, supply pressure of the fuel gas can be suitably changed corresponding to the operation status of the fuel cell, and response can be improved.

摘要： FC current control in a fuel cell operation system can be roughly divided into two parts. The first part executes a total air feed amount calculation step, an FC air amount calculation step, and a bypass air amount calculation step. These steps are executed by using a stoichiometry map and a pumping hydrogen amount map. The second part calculates a control valve open amount instruction value and a bypass valve open amount instruction value according to the calculated FC air amount and the bypass air amount. Here, a control valve open amount map and the like are used. When generated power is output from the fuel cell stack by these instruction values, the actual FC current value is compared to the FC current instruction value and the control valve open amount is corrected according to a difference between them.
