[PROBLEMS] It is possible to generate power for a long time with high power density by activation for a short time, and it is possible to eliminate the need for introduction of a carrier gas during power generation, so that the power generation system can be made more compact. Provided is a solid oxide battery that can be used. A solid oxide battery comprising at least an anode having an anode material, a cathode having a cathode material, and an electrolyte composed of an ion conductive solid oxide disposed between the anode and the cathode. The anode material is a composite metal oxide or cermet, solid carbon is supported on the anode material at the time of activation, and at the time of power generation, power generation is performed using at least the following reaction formulas (1) and (2). A solid oxide battery characterized. CO 2 + C → 2CO (1) CO + O 2− → CO 2 + 2e − (2) [Selection figure] None |
