| 摘要 |
A fuel cell system has a fuel cell stack (12) including a plurality of fuel cells that are stacked together, a heat transfer layer (14) that covers the fuel cell stack (12) and is formed at its periphery with recesses, and a low heat transfer layer (16) disposed in each of the recesses and having a low thermal conductivity. The low heat transfer layer (16) is fixed to a casing (18) such that the low heat transfer layer (16) closely contacts with the heat transfer layer (14) when the fuel cell stack (12) reaches its normal operating temperature, and such that the low heat transfer layer (16) is spaced apart from the heat transfer layer (14) due to thermal contraction during a process in which the temperature of the fuel cell stack (12) decreases from the normal operating temperature to the ambient temperature. |
