Challenge on energy resources exists, especially when the fossil resources are limited. Fuel cells, as an alternative replacement, can be used. Fuel cells with coated bipolar plates are the interest of this paper. Current research is concerned with the effects of CrN/TiN coatings on interfacial contact resistance (ICR). Stainless steel 410 was selected as a base metal, and the coating process was performed using chromium nitride and titanium nitride by cathodic arc evaporation method. It was found that the surface roughness and ICR values of CrN-coated sample are lower than the TiN-coated sample. The concluded that the CrN layer could be replaced with the TiN layer for better performance of bipolar plates. |
