摘要： The standard permeation amount of an impurity substance, that is, the permeation amount per unit area of the impurity substance under a standard concentration is calculated from the gas pressures in the gas channels, the impedance, and the fuel cell temperature. The permeation index of the impurity substance at each of locations in the anode-side gas channel is calculated on the basis of the previously calculated value of the concentration distribution of the impurity substance. Then, on the basis of the standard permeation amount and the permeation index, the permeation amounts of the impurity substance at the locations in the anode-side gas channel are calculated. On the basis of a total of the permeation amounts, the amount of the impurity substance accumulated in the anode-side gas channel is calculated. Furthermore, the distribution of existence rate of the impurity substance in the anode-side gas channel is calculated on the basis of the gas pressure in the anode-side gas channel and the electric current value.

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： The present invention has been devised in order to solve the problems described above, and an object of the present invention is to provide a fuel cell system that can discharge an impurity in an anode gas flow channel while suppressing wasteful discharge of a fuel gas to the outside of the system. An exhaust valve is connected to a downstream end of an anode gas flow channel of a fuel cell. The exhaust valve has an exhaust mode in which a substantially smaller amount of gas than the consumption of a fuel gas in the anode gas flow channel is discharged to the outside of the system. After a request to stop electric power generation by the fuel cell, the output current value of the fuel cell is increased to a predetermined value. Then, the exhaust valve is set in the exhaust mode before or when the output current value is increased, and the discharge flow rate of the exhaust valve is increased in accordance with the increase of the output current value.

摘要： A fuel cell system includes a controller that estimates or detects an air replacement state of a fuel electrode and a hydrogen circulation path while the operation of the fuel cell system is stopped. Upon starting the fuel cell system, the controller changes the order in which the operation of a hydrogen circulation pump is started and a hydrogen pressure regulator is opened to start the supply of hydrogen gas on the basis of the estimated or detected air replacement state, thereby preventing deterioration caused by uneven distribution of air and hydrogen in the fuel electrode.

摘要： A direct oxidation fuel cell system includes a fuel cell and a cooling device. An anode-side separator of the fuel cell has a fuel flow channel in the face in contact with the anode. The direction of a flow of air supplied by the cooling device is set so that the upstream-side portion in the average flow direction of fuel in the fuel flow channel is selectively cooled. This allows the upstream-side portion of the polymer electrolyte membrane having large MCO to be cooled, thereby reducing the amount of MCO. Also, the downstream-side portion where the fuel concentration in the fuel flow channel is low has a relatively high temperature, thereby making it possible to improve the energy conversion efficiency.
