Publication number: 20090317705Abstract: 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.Type: ApplicationFiled: June 20, 2008Publication date: December 24, 2009Applicant: GENERAL ELECTRIC COMPANYInventors: Matthew Joseph Alinger, Frederic Joseph Klug, James Anthony Ruud, Stephane Renou, Reza Sarrafi-Nour
