<P>PROBLEM TO BE SOLVED: To provide a fuel cell system which can suppress an overvoltage and furthermore deterioration of a fuel cell even if supply delay of reaction gas occurs at starting time. <P>SOLUTION: This is the fuel cell system having the fuel cell to generate electric power by electrochemical reaction of a reaction gas, and a control part to control power generation state of the fuel cell. The control part compares high-potential evasion target output that is decided in high-potential evasion control wherein it is suppressed that power generation voltage of the fuel cell becomes to have a prescribed high-potential evasion voltage threshold value or more at the time of the starting of the fuel cell with fuel cell allowance output decided based on reaction gas stoichiometry. The fuel cell is controlled by the fuel cell power generation command value which is decided based on either one output out of larger output out of these high-potential evasion target output and fuel cell allowance output. <P>COPYRIGHT: (C)2009,JPO&INPIT |
