。[Problems to be solved by the invention] However, because the conventional 5OFC module needs to be operated at a high temperature of about 1000°C due to the characteristics of the fuel cell itself, it is difficult to maintain the temperature and recover heat from high-temperature exhaust gas. Plato is essential for improving performance. However, in the conventional 5OFG module, a heat insulating material 2 is inserted inside the module outer shell 1 made of steel plate to suppress the heat dissipation, and an air preheater installed outside is used to preheat the reaction air. Due to the structure in which it is supplied to the module shell 1, the insulation material 2 occupies a considerable space within the module shell 1. In addition, not only is an air preheater required outside the module outer shell 1, but the piping with the module outer shell 1 is also required.
(700 to 900°C), resulting in an increase in the amount of heat dissipated.
