摘要： A fuel cell system can be initiated in shorter time while minimizing the deterioration of a fuel cell. 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.

摘要： A fuel cell system that has a fuel cell stack with a plurality of laminated cells, each of the laminated cells includes an electrolyte membrane interposed between a fuel electrode receiving a supply of fuel gas and an oxidizing agent electrode receiving a supply of oxidizing agent gas. 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： 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).

摘要： A fuel cell stack (1) comprises a reactive gas passage (115, 1c, 116, 1a) and a water passage (117, 1b) substantially parallel thereto, and a reactive gas is humidified by water permeating from the water passage (117, 1b) through a porous member (112a, 112c). The pressure reduction amounts in the reactive gas passage (115, 1c, 116, 1a) and the water passage (117, 1b) are respectively calculated based on the power generation load of the stack (1). From the pressure reduction amounts in the water passage (117, 1b) and the reactive gas passage (115, 1c, 116, 1a), the pressure of the reactive gas supplied to the reactive gas passage (115, 1c, 116, 1a) is controlled such that the difference in pressure between the reactive gas passage (115, 1c, 116, 1a) and the water passage (117, 1b) is within a predetermined range, whereby the reactive gas is humidified in a desirable state.
