Abstract
A solid oxide regenerative fuel cell system is used to supply power in a fuel cell mode and to generate a hydrocarbon fuel in an electrolysis mode. The system includes a solid oxide regenerative fuel cell and a reactor adapted to convert an exhaust emitted from the solid oxide regenerative fuel cell to a hydrocarbon gas when the solid oxide regenerative fuel cell operates in an electrolysis mode.
