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： 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： In a fuel cell system (10), an anode exhaust gas discharge pipe (50) is full of hydrogen at the start of operation of a fuel cell (20). As time passes when the fuel cell (20) is operating, the concentration of impurities within the anode exhaust gas discharge pipe (50) increases. When the hydrogen concentration is less than a reference concentration for opening a valve, an upstream cut-off valve (61) closes and a downstream cut off valve (62) opens. As a result, the impurity concentration in the anode gas discharge pipe (50) quickly drops and is restored to the level that it was at the start of operation of the fuel cell (20). This sudden drop in the impurity concentration is caused by a pressure difference between the pressure in the anode exhaust gas pipe (50) and the pressure of the outside air, and the concentration gradient.

摘要： A fuel cell system capable of proper driving even at times of low temperature, below freezing or the like. The fuel cell system includes a fuel cell stack, piping, a pressure regulator, and a control unit. The piping discharges hydrogen or air that is used in electricity generation from the fuel cell stack. The pressure regulator regulates pressure of gases which are supplied and discharged to and from the fuel cell stack in accordance with the size of a load. The control unit judges whether or not there is a likelihood of the pressure regulator freezing, and when it is judged that there is a likelihood of freezing, prohibits a degree of openness of the pressure regulator from going below a predetermined degree of openness.

摘要： When an operation of a fuel cell system (100) is stopped, a flow of cathode off-gas into a circulation passage (28) is stopped. A stopped state of the flow of the cathode off-gas into the circulation passage (28) is held even after a start-up of the system (100) until the fuel cell (10) is brought into a predetermined state. Such structure prevents an outlet (52) of a three-way valve (50) from being frozen in an opened state. Accordingly the cathode off-gas that contains large amount of water and nitrogen hardly flows into the fuel cell (10) accidentally. This makes it possible to restrain various types of trouble, for example, generation of flooding upon start-up of the system, decrease in the oxygen partial pressure, and decrease in the power generation efficiency resulting therefrom.
