摘要： A fuel cell system includes a fuel cell stack comprising an anode (fuel electrode) and a cathode (oxidizer electrode), and a system startup run is conducted at the system startup to bring the fuel cell stack into a power extractable state (idle state). In the fuel cell system, air supply flow is controlled so that air in an amount larger than a reference flow required to bring the fuel cell stack into the power extractable state, is supplied to the cathode over a preset time from the start of air supply to the cathode, by estimating an amount of hydrogen present on the cathode, deciding an air supply flow increment to commensurate with the estimated hydrogen amount, and controlling an air supply flow, whereby air at a flow rate provided by adding the decided increment to the reference flow, is supplied to the cathode during the system startup run, thereby allowing to effectively restrict a disadvantage in that a high concentration of hydrogen is wasted during the system startup run, without deteriorating the efficiency of the fuel cell system.

The fuel cell system includes a fuel cell stack having a fuel electrode, an oxidizer electrode and an electrolyte membrane disposed there between, the fuel cell producing electricity by an electrochemical reaction of a fuel gas and an oxidizer gas, which are supplied to the fuel electrode and the oxidizer electrode, respectively; a fuel gas supplying device for supplying the fuel gas to the fuel cell stack; an oxidizer gas supplying device for supplying the oxidizer gas to the fuel cell stack; a current controlling device for extracting a current from the fuel cell stack; and a voltage sensor disposed in at least two of the fuel cell stacks. A controller controls the current controlling device such that a minimum voltage, which is obtained from the voltage sensor after a fuel gas is supplied to the fuel electrode without supplying the oxidizer gas to the oxidizer electrode at the time of initiating, becomes zero volts or more. Then, the oxidizer gas is supplied to the oxidizer to start producing electricity.

A fuel gas supply device supplies a fuel gas to the fuel electrode. An oxidizing agent gas supply device supplies an oxidizing agent gas to the oxidizing agent electrode. A fuel electrode side discharge system discharges a discharge gas from the fuel electrode to an external. A circulation device re-circulates the discharge gas discharged from the fuel electrode into an upstream side of the fuel electrode.

摘要： The ice prevention system of the present invention utilizes, in combination, a de-ice subsystem and anti-ice subsystem in a new configuration on an aircraft with engines located behind its wings. Depending on the vertical location of the engines with respect to the wings, the anti-ice subsystem is configured on an upper or lower portion of a leading edge of the wings. If the engine is located above the wing, the anti-ice system is configured only on a section of the wing aligned with the engine and only on the upper portion of the leading edge. If the engine is located below the wing, the placement of anti-ice system is reversed. The de-ice subsystem is configured on the opposite portion of the leading edge adjacent to the anti-ice subsystem and on the remainder of the leading edge of the wing.

摘要： The present invention provides a fuel cell system having means for controlling the flow of coolant within a fuel cell system. A desirable rate of flow of coolant is created, during power generation, by determining the difference in temperature between coolant flowing into individual cell sets of the fuel cell assembly and the temperature of coolant exhausted from the cell assembly. The fuel cell system features controls adapted to evaluate the heat generation state of each fuel cell set and to regulate the temperature of cell sets by controlling the rate circulation of the coolant.
