A fuel cell system has a first boost converter of a fuel cell, a second boost converter of a secondary battery, and a control unit. Output sides of the first boost converter and the second boost converter are connected so as to be the same potential. The control unit is configured to, when detecting failure of the second boost converter, cause input and output sides of the second boost converter to conduct, estimate an open circuit voltage of the secondary battery based on a state of charge, and execute electric power consumption by an accessory that operates by electric power supplied from the fuel cell when determining that the first boost converter is not able to boost the output voltage of the fuel cell to the open circuit voltage, and stops the electric power consumption by the accessory when determining that the first boost converter is able to boost.
