摘要： The invention definitely detects and cancels poisoning of a electrocatalyst in a fuel cell without delay. A first temperature sensor (61) and a second temperature sensor (63) are disposed respectively at an inlet and an outlet of first channels (34p) for gaseous fuel in a fuel cell (10). An electronic control unit (70) receives detection signals from the temperature sensors (61,63) and estimates a degree of poisoning of electrocatalyst on an anode (32) based on the detection signals. When determining that the electrocatalyst is poisoned, the electronic control unit (70) controls on and off first through fourth solenoid valves (51-54) to change the flow direction of the gaseous fuel through the first channels (34p). This allows a place with electrocatalyst poisoning to be exposed to the gaseous fuel having a relatively low concentration of carbon monoxide.
