<P>PROBLEM TO BE SOLVED: To determine hydrogen leakage without impairing durability of a fuel cell at starting of the fuel cell. <P>SOLUTION: The fuel cell system is provided with a fuel cell generating power by electrochemical reaction between fuel gas and oxidant gas, and a control part determining leakage of fuel gas. The control part includes a starting means for starting the fuel cell by raising the voltage of the fuel cell from a starting voltage to an operation voltage which is lower than an open-circuit voltage, and a leakage determining means for determining leakage of fuel gas before the voltage of the fuel cell reaches the operation voltage at starting of the fuel cell. <P>COPYRIGHT: (C)2011,JPO&INPIT |
