PURPOSE:To improve the system efficiency and miniaturize a system by incorporating a means preheating the reaction gas in a fuel cell. CONSTITUTION:The anode gas is fed to anodes of cell main bodies 1 from manifolds 6 and discharged via manifolds 7 after contributing to power generation, and the cathode gas is fed from a manifold 5 and fed to a preheater 2 for preheating. The preheated cathode gas is fed to cathodes of the cell main bodies 1 via a manifold 3 and discharged from manifolds 4 after contributing to power generation. No heat exchanger is required to be provided outside the cell, and no electric power for preheating the reaction gas is required. The heat exchanging efficiency is improved, the system efficiency is improved, and the system can be miniaturized. |
