摘要： A method for the formation of a diffusion barrier layer on a surface of at least one fuel cell interconnect structure is described. The interconnect structure is usually formed from ferritic stainless steel, and includes chromium. The method includes the step of coating an austenite phase-stabilizer on the interconnect surface, and then heating the coated surface. The heat treatment transforms the microstructure of the surface region of the interconnect, from a substantially ferritic body-centered cubic (BCC) phase to a substantially austenitic face-centered cubic (FCC) phase. The diffusion rate of chromium through the FCC phase is relatively low. Thus, the formation of a thick layer of chromium oxide can be minimized, leading to better fuel cell performance. Related fuel cells and fuel cell stacks are also disclosed.

摘要： Disclosed herein are a system and a method for the production of hydrogen. The system advantageously combines an independent high temperature heat source with a solid oxide electrolyzer cell and a heat exchanger located between the cathode inlet and the cathode outlet. The heat exchanger is used to extract heat from the molecular components such as hydrogen derived from the electrolysis. A portion of the hydrogen generated in the solid oxide electrolyzer cell is recombined with steam and recycled to the solid oxide electrolyzer cell. The oxygen generated on the anode side is swept with compressed air and used to drive a gas turbine that is in operative communication with a generator. Electricity generated by the generator is used to drive the electrolysis in the solid oxide electrolyzer cell.
