Abstract
A fuel cell system ensures estimation on a cooling capacity by produced water in an intercooler when water is provided. A control device in a fuel cell system includes a freeze determination unit, a required pressure calculator, a discharge pressure setting unit, a power supplying unit, and a melting estimation unit. The freeze determination unit determines a freezing of produced water in an intercooler. The required pressure calculator calculates a pressure of air discharged from an air compressor. The discharge pressure unit sets the discharge air compressor to a melt pressure when the required pressure is the melt pressure or more. The power supplying unit performs power generation with the melt pressure for a melting period set to melt the frozen produced water, and supplies the generated power to the motor. The unit estimates the melting of the frozen water in the intercooler has completed after the melting period.
