Abstract: A valve-closing pressure chamber and a valve-opening pressure chamber are arranged on both sides of a main diaphragm inside an outlet shutoff valve. An upper supply/discharge tube and a lower supply/discharge tube are connected to a housing forming the outlet shutoff valve. The upper and lower supply/discharge tube supply and discharge air to and from the valve-closing pressure chamber and the valve-opening pressure chamber, respectively. An opening end, which is on the pressure chamber side, of each supply/discharge tube is obliquely cut relative to the direction of axis of the supply/discharge tube, which increases the opening area of the opening end. This prevents water present in the pressure chamber from adhering to the opening end of each supply/discharge tube and prevents the adhered water from freezing. As a result, operation performance of the outlet shutoff valve is enhanced.

Abstract: It is prevented that when a system is left unused, carried carbon ion a cathode-side catalyst to lower a power generation performance. The molar quantities of hydrogen and oxygen in a fuel gas supply/discharge system and an oxidizing gas supply/discharge system with respect to a fuel cell are calculated, and control is performed so that the molar ratio of hydrogen and oxygen which can chemically be reacted in a fuel gas and an oxidizing gas during the stop of the fuel cell is 2 or more. Hydrogen is preferably supplied in accordance with the magnitude of a cell voltage in the fuel cell so as to maintain the molar ratio. Moreover, a gas passage in the oxidizing gas supply/discharge system is preferably provided with an inlet valve and an outlet valve for sealing the oxidizing gas in the gas passage.

Abstract: A valve-closing pressure chamber and a valve-opening pressure chamber are arranged on both sides of a main diaphragm inside an outlet shutoff valve. An upper supply/discharge tube and a lower supply/discharge tube are connected to a housing forming the outlet shutoff valve. The upper and lower supply/discharge tube supply and discharge air to and from the valve-closing pressure chamber and the valve-opening pressure chamber, respectively. An opening end, which is on the pressure chamber side, of each supply/discharge tube is obliquely cut relative to the direction of axis of the supply/discharge tube, which increases the opening area of the opening end. This prevents water present in the pressure chamber from adhering to the opening end of each supply/discharge tube and prevents the adhered water from freezing. This in turn prevents the opening end of the supply/discharge tube from being closed or the opening area from being reduced. As a result, operation performance of the outlet shutoff valve is enhanced.

Abstract: An inlet shut valve or an outlet shut valve has a main diaphragm and a sub-diaphragm, wherein a valve closing pressure chamber and a valve opening pressure chamber are provided, respectively, on the upper surface side and the lower surface side of the main diaphragm. Furthermore, an atmospheric pressure chamber and a pressure chamber constituting a channel are provided, respectively, on the upper surface side and the lower surface side of the sub-diaphragm. A drive shaft constituting a valve element is driven in the direction for bringing about a valve open state by both forces, i.e. a first force acting by pressure difference between the valve closing pressure chamber and the valve opening pressure chamber and a second force acting by pressure difference between the atmospheric pressure chamber and the pressure chamber constituting a channel and acting in the same direction as the first force.

Abstract: A fuel cell system is equipped with an airflow meter that measures an amount of a supplied cathode gas, and a hydrogen circulation pump. A controller instructs the fuel cell to perform a preset reference operation, measures the power consumed by the hydrogen circulation pump, and determines the amount of the supplied cathode gas appropriate for the amount of power consumed by the hydrogen circulation pump. The controller then calculates, the measurement error in the airflow meter and correction value for the measurement error. The controller controls the amount of the supplied cathode gas based on the value measured by the airflow meter after being corrected with the correction value.

Abstract: A shutoff value provided on the entrance side and exit side of a fuel cell system has a diaphragm. A valve closing-side pressure chamber is provided on the upper face side of the diaphragm, and a valve opening-side pressure chamber is provided on the lower face side of the diaphragm. With the valve closing-side pressure chamber of the shutoff valve pressurized, the pressure in the chamber is maintained by ViS, Vic, and ViO in an electrically non-conducted state. Also, the pressure in the valve opening-side pressure chamber of the shutoff valve is maintained released. By this, force acting in the direction of closing a valving element acts on it through the diaphragm, maintaining the shutoff valve closed.

Abstract: A fuel cell system has shutoff valves installed between an air flow channel in a fuel cell and the atmosphere. The shutoff valves have valve seats and also have valve discs for sealing in air by coming into contact with the valve seats. The valve discs are adapted to be sucked toward the valve seats by negative pressure in the air flow channel in the fuel cell. The fuel cell system further has an atmosphere release valve installed between the air flow channel in the fuel cell and the shutoff valve and releasing negative pressure in the air flow channel in the fuel cell to the atmosphere. When the fuel cell is started, the shutoff valves are opened after the negative pressure in the air flow channel of the fuel cell is released. Consequently, sealing ability of the shutoff valves when the fuel cell is stopped is improved, and easiness of opening of the shutoff valves when the fuel cell is started is also improved.

An upper supply/discharge tube and a lower supply/discharge tube are connected to a housing forming the outlet shutoff valve. The upper and lower supply/discharge tube supply and discharge air to and from the valve-closing pressure chamber and the valve-opening pressure chamber, respectively. An opening end, which is on the pressure chamber side, of each supply/discharge tube is obliquely cut relative to the direction of axis of the supply/discharge tube, which increases the opening area of the opening end.

This in turn prevents the opening end of the supply/discharge tube from being closed or the opening area from being reduced. As a result, operation performance of the outlet shutoff valve is enhanced.
