PURPOSE:To provide a temperature regulator of a fuel cell which heat transfer can be made between the fuel cell itself and the outer side by allowing to circulate naturally a hat medium. CONSTITUTION:Heat generated in stacked fuel cells 8a and 8b is transferred to a1 and a cooling plate b3 from the upper and lower sides, and then transferred to a cooling pipe 5 placed between two cooling plates 1 and 3. This heat vaporizes a heat medium sealed in the cooling pipe, and this heat medium vapor flows in a heat medium flowing path and the heat is released to the outside at a heat releasing apparatus 7 located at higher place than that of the cooling pipe 5. The vapor is condensed to liquid and the liquid returns by gravity to the cooling pipe 5 in the cooling plates 1 and 3. Circulation of heat medium can be made without using an auxiliary power. |
