Abstract
A fuel cell system comprising a fuel cell that generates electricity through an electrochemical reaction between a fuel gas and an oxidant gas, and a control portion that controls amount of electricity generation at a time of starting the fuel cell, characterized in that the control portion has voltage drop control means for controlling speed of dropping a starting voltage of the fuel cell from an open-circuit voltage to a high-potential-avoiding voltage according to an initial voltage of the fuel cell and to a pre-determined threshold voltage that is lower than the high-potential-avoiding voltage, when the starting voltage of the fuel cell is dropped from the open-circuit voltage to the high-potential-avoiding voltage.
