摘要： The present invention details a process for producing a catalyst powder. The steps of the process include preparing catalyst slurry, drying, pyrolyzing, and calcining the catalyst slurry to obtain a calcined catalyst powder. The catalyst slurry comprises a catalyst, a liquid carrier, a templating agent, and a catalyst substrate. The catalyst slurry is dried to obtain a raw catalyst powder. The raw catalyst powder is heated in a first controlled atmosphere to obtain a pyrolyzed catalyst powder and the pyrolyzed catalyst powder is calcined in a second controlled atmosphere to obtain a calcined catalyst powder. A method of fabricating a catalyst surface and catalytic converter using the prepared catalyst powder is also illustrated.

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.
