Abstract: One variation of an electrolyzer system includes a skid loaded with a set of modules including a feed-supply module, configured to generate a feed mixture of carbon dioxide and water, and, an electrolysis module including: a cell stack arranged within an insulated housing and configured to receive metered volumes of the feed mixture from the feed-supply module to generate a fuel mixture of syngas, water, and carbon dioxide via electrolysis; and a set of heating elements configured to regulate temperature of the cell stack within a target temperature range and regulate temperatures of the feed mixture, the air mixture, and the fuel mixture within the insulated housing. The skid can further include: a processing module configured to extract syngas from the fuel mixture received from the electrolysis module; and a power module configured to drive a voltage across the cell stack to promote electrolysis of the feed mixture.

Abstract: One variation of a contact material includes: a base material including a first amount of Lanthanum, a second amount of Nickel, and a third amount of Oxygen; a fourth amount of a first doping agent configured to stabilize a crystal structure of the base material; and a fifth amount of a second doping agent, in the set of doping agents, configured to limit thermal expansion of the base material. The contact material exhibits: a thermal expansion coefficient between 10.0×10?6K?1 and 15.0×10?6K?1 at temperatures between 25 degrees Celsius and 1100 degrees Celsius; and an electrical conductivity greater than 200 Siemens-per-centimeter at temperatures within a temperature range of 700 degrees Celsius to 1300 degrees Celsius.

Abstract: Novel mixed-conducting perovskite oxides, including La0.3Ca0.7Fe0.7Cr0.3O3-?, useful as oxygen and fuel electrodes for solid oxide fuel cells (SOFCs) and reversible solid oxide fuel cells (RSOFCs) applications. Electrode materials produce by microwave-assisted processes show improved properties as electroactive materials. SOFC and RSOFC are successfully prepared using microwave-assisted techniques.
