PROBLEM TO BE SOLVED: To provide a small-sized fuel cell device having a simplified structure that can improve heat exchange efficiency.SOLUTION: A fuel cell device comprises a fuel cell 23 for generating power using oxygen-containing gas and fuel gas, a first heat exchange part 8a for exchanging heat between exhaust gas from the fuel cell 23 and the oxygen-containing gas, and a second heat exchange part 8b for exchanging heat between the exhaust gas and a heat medium other than the oxygen-containing gas. The first heat exchange part 8a and the second heat exchange part 8b are stored in one casing 8c, and the exhaust gas runs sequentially from the first heat exchange part 8a to the second heat exchange part 8b. |
