A method of operating a fuel cell electrochemical system includes receiving at least one of a cost of electricity and a cost of fuel and adjusting at least one of an operating efficiency and throughput of the fuel cell based on the at least one of the received cost of electricity and the received cost of fuel.
摘要:
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.

摘要:
A Solid Oxide Regenerative Fuel Cell (SORFC) system stores waste heat from the fuel cell in a heat storage material during the discharge mode. The heat is then used to heat water to be electrolyzed during the charge mode.
摘要:
A fuel cell system includes a plurality of fuel cells, a plurality of interconnects, and a hydrogen separation device, wherein the hydrogen separation device separates hydrogen from the fuel cell stack anode exhaust. The separated hydrogen is then reintroduced into the fuel cell stack to optimize overall system efficiency. Monitoring of the performance of the hydrogen separation device gives an indication as to the fuel cell system performance.
