Abstract:
An interconnect and gas separator for a solid oxide fuel cell includes a cermet material comprising a first conductive phase and a second ceramic phase or a multi-component ceramic material including a first ceramic ionically conductive and electrically non-conductive component and a second ceramic electrically conductive component.
Abstract:
A ceramic electrolyte for a solid oxide fuel cell includes at least one non-uniform surface portion. Preferably, the electrolyte surface is textured.
Abstract:
A method of making a solid oxide fuel cell (SOFC) includes providing a solid oxide electrolyte and depositing at least one electrode on the electrolyte by PVD, such as sputtering. A method of making an interconnect for a fuel cell stack includes providing an electrically conductive interconnect, and depositing a layer on the interconnect by PVD, such as depositing a LSM barrier layer by sputtering. The SOFC and the interconnect may be located in the same fuel cell stack.
Abstract:
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.
Abstract:
A water purification system includes a fuel cell stack, a steam generator, and a water purification unit. The fuel cell stack is adapted to provide heat to the steam generator and the steam generator is adapted to provide steam to the water purification unit.
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.

Abstract:
A method of operating a high temperature fuel cell system containing a plurality of fuel cell stacks includes operating one or more of the plurality of fuel cell stacks at a first output power while operating another one or more of the plurality of the fuel cell stacks at a second output power different from the first output power.
