<P>PROBLEM TO BE SOLVED: To provide a technique capable of restraining a hydrogen separation film from getting brittle during the period of stopping of the operation of a fuel cell system, and capable of preventing the fuel cell system from damage caused by a combustion reaction generated when stopping the fuel cell system. <P>SOLUTION: The fuel cell system is provided with a hydrogen separation part, a fuel cell, a gas flow passage setting part capable of setting propriety of gas flow between the hydrogen separation part and an anode side passage, and an air supply part supplying air to the hydrogen separation part in order to remove hydrogen gas in the hydrogen separation part. A control part sets the gas flow passage setting part in a state that gas is stopped from flowing through the hydrogen separation part and the anode side passage when stopping the operation of the fuel cell system, and air is supplied to the hydrogen separation part in a state that the air is not supplied in the anode side passage by controlling the air supply part. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
