PROBLEM TO BE SOLVED: To provide a solid oxide type fuel battery system that suppress excessive temperature increase in a vaporization mixer (vaporization mixing chamber) with a relatively simple construction.SOLUTION: A solid oxide type fuel battery system comprises a vaporization mixer 4 for vaporizing reforming water and mixing water vapor and raw fuel gas, a reformer 6 for reforming mixture gas from the vaporization mixer 4 with water vapor, and a cell stack 8 for generating power by oxidation and reduction of reformed fuel gas from the reformer 6 and oxidation material. Surplus fuel gas exhausted from the cell stack 8 is combusted by surplus oxidation material, and the vaporization mixer 4 and the reformer 6 are heated by using combustion heat of the combustion. The vaporization mixer 4 is filled with mixing material 62 for promoting vaporization of the reforming water and mixing generated water vapor and raw fuel gas into mixture gas, and a reforming material 64 on which reforming catalyst for reforming the generated mixture gas with water vapor is carried.SELECTED DRAWING: Figure 2 |
