Abstract
A controller of a FC system disclosed herein may be configured to: (1) start both of first and second FC stacks when a measured value of a gas sensor is lower than a first concentration: (2) maintain both of the first and second FC stacks stopped when the measured value is higher than a second concentration which is higher than the first concentration; and (3) when the measured value is from the first concentration to the second concentration, supply the fuel gas to the first FC stack while maintaining supply of the fuel gas to the second FC stack stopped, thereafter stop supply of the fuel gas to the first FC stack when a pressure in the first FC stack reaches a pressure threshold, and thereafter start the first FC stack when the pressure in the first FC stack after a predetermined time is higher than a pressure lower limit.
