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.
Abstract:
A high temperature electrochemical system, such as a solid oxide fuel cell system, generates hydrogen and optionally electricity in a fuel cell mode. At least a part of the generated hydrogen is separated and stored or provided to a hydrogen using device. A solid oxide regenerative fuel cell system stores carbon dioxide in a fuel cell mode. The system generates a methane fuel in an electrolysis mode from the stored carbon dioxide and water by using a Sabatier subsystem. Alternatively, the system generates a hydrogen fuel in an electrolysis mode from water alone.
