A cooling apparatus for a fuel cell system having high cooling efficiency. The cooling apparatus includes a chemical heat pump circuit using isopropyl alcohol, acetone, and hydrogen gas as a heat carrier. The chemical heat pump circuit includes an endothermic device incorporated in the fuel cell and an exothermic device for releasing heat from the circuit. The temperature of a heat carrier is increased to a first temperature by the heat of the fuel cell. The chemical heat pump circuit uses the heat of the heat carrier after it is heated to the first temperature to heat the heat carrier to a second temperature, which is higher than the first temperature. The heat of the heat carrier is used for other useful purposes or is simply desorbed. After the heat carrier is heated to the second temperature, the heat carrier is easily cooled by a cooling fan. Thus, the cooling apparatus has a high cooling efficiency.
