摘要： A fuel cell system and a method for scavenging it are provided. The fuel cell system includes a fuel cell, a fuel gas passage, an oxidant gas passage, a communicating passage, a communicating valve, a monitoring device, a valve controller, a scavenging device and a computing device. The monitoring device monitors a state transition of the fuel cell after a termination of power generation. The valve controller opens the communicating valve when a signal indicative of the state transition meets a predetermined criterion. The scavenging device includes a first scavenging device for the oxidant gas passage, and a second scavenging device for the fuel gas passage. The computing device computes an amount of the oxidant gas required for scavenging according to a system shut off time. The scavenging device conducts scavenging with the amount of the oxidant gas obtained by the computing device.

摘要： A fuel cell system includes a fuel cell having a fuel gas flow path and an oxidant gas flow path; a compressor for supplying humidified air to the oxidant gas flow path; a back-pressure regulating valve for controlling pressure of humidified air in the oxidant gas flow path; a pressure sensor for measuring the pressure of the humidified air in the oxidant gas flow path; and a control section for controlling the compressor and the back-pressure regulating valve. In this system, the pressure of humidified air in the oxidant gas flow path is regulated to become equal or approximate to a target pressure by the back-pressure regulating valve. When the pressure difference between the pressure measured by the pressure sensor and the target pressure is larger than a predetermined pressure difference, the control section corrects operating conditions of the compressor, so that the measured pressure becomes the target pressure.
