PROBLEM TO BE SOLVED: To provide a fuel battery system that is excellent in power generation efficiency and enhanced in reliability because of simplification of the system.SOLUTION: A fuel battery system includes a reformer for generating reformed gas by reforming carbon dioxide, a first fuel battery for generating electric power using the reformed gas supplied from the reformer, a carbon dioxide separation membrane for separating carbon dioxide from off-gas containing unreacted reformed gas discharged from the first fuel battery, a second fuel battery which is disposed at the downstream side of the carbon dioxide separation membrane and performs power generation using the off-gas from which carbon dioxide is separated, and a raw material gas supply path that is disposed at the transmission side of the carbon dioxide separation membrane and supplying the reformer with the carbon dioxide separated by the carbon dioxide separation membrane and the raw material gas.SELECTED DRAWING: Figure 1 |
