摘要： A fuel cell system has a purge valve that adjusts the amount of nitrogen in a hydrogen circulation channel and a fuel electrode to be discharged through a discharge channel. A purge rate correcting unit variably sets a target control value of the nitrogen content in the hydrogen circulation channel and the fuel electrode by taking into account whether a driving mode is set in a normal power generation mode or an idle mode. An opening of the purge valve is controlled on the basis of the target control value.

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. A voltage limit device limits a voltage across the fuel cell stack by drawing a current from the fuel cell stack at a time of an activation of the fuel cell system. A controller halts the supply of the oxidizing agent gas to the oxidizing agent electrode from the oxidizing agent gas supply device at the time of the activation of the fuel cell system, inhibits a discharge of the discharge gas to the external through the fuel electrode side discharge system, and starts the supply of fuel gas to the fuel electrode from the fuel gas supply device in a state where the discharge gas is circulated through the circulation device.
