Abstract:
1. A fuel cell system comprising: a fuel cell which has a catalyst layer therein and which receives supply of a first reactive gas and a second reactive gas to generate a power; and a refrigerant system which supplies a refrigerant to the fuel cell to control a temperature of the fuel cell, and which includes a control section programmed to control the refrigerant system, wherein the control section is programmed such that, when a presumed temperature of the fuel cell during the next system start or a temperature having a correlation with the temperature of the fuel cell is a predetermined temperature or less, the control section instructs the refrigerant system to stop a supply of the refrigerant during system stop, and to resume the supply of the refrigerant after elapse of a predetermined time while allowing the fuel cell to generate the power in a state in which a supply of the first reactive gas to the fuel cell is blocked, and wherein the control section is further programmed to control the supply of the refrigerant to the fuel cell so that a temperature difference between the fuel cell and the refrigerant to be supplied to the fuel cell has a predetermined value or less.
