Electrochemical properties of NiO

The corrosion resistance of 316L stainless steel coated with NiO-YSZ (Ni added yttria stabilized zirconia) was examined in a proton exchange membrane fuel cell (PEMFC) environment. The NiO-YSZ coating was carried out using a sol-gel dip coating method, and the corrosion resistance and interfacial contact resistance (ICR) were determined by the composition and morphology of the NiO-YSZ film.

Electrochemical Performance Testing and Characterization

Abstract: 316L stainless steels are the most promising materials for use as bipolar plates in proton exchange membrane fuel cells (PEMFC) because of their low cost, light weight, convenience of machining, ease of shaping into thin sheets, excellent electrical

Considerations for Stainless Steel Bipolar Plate

Stainless steel plates are a viable option for bipolar plates due to material properties, manufacturability, and cost. The five major steps that need to be carefully selected, engineered and developed are the (1) material type, (2) oxide formation or removal, (3) manufacturing process, (4) correct coating material, and (5) proper coating manufacturing process.

Final Report Summary

Furthermore, the cell with the gold-coated plate is as good as the lowest cell built from graphite bipolar plates, while the cells build from pvd-coated plates are somewhat lower. From the single cell tests it can be seen that it is possible to reach almost a similar performance to that of graphite bipolar plates if stainless steel bipolar plates are used with a noble metal free coating.
