By using electrochemical techniques, the electrochemical characteristic of Cr-based film coated 304 stainless steel (304SS) as proton exchange membrane fuel cell (PEMFC) bipolar plates, which was deposited by cathodic arc deposition technology, was studied. The results indicated that Cr, CrN, (TiCr)N and (TiN+Ti) film could not only decreased the steel’s contact resistance but also improved its corrosion resistance and the fuel cell stack’s performance. Since Cr, (CrN) and (TiCrN) film were more compact than (TiN+Ti) film, which contained the oxides of Ti, as bipolar plates, the performance for all film change in the following order: Cr film ≈(CrN) film ≈ (TiCrN) film >(TiN+Ti) film.

Effective Distribution

Proton exchange membrane fuel cell (PEMFC) system is an advanced power system for the future that is sustainable, clean and environmental friendly. The flow channels present in bipolar plates of a PEMFC are responsible for the effective distribution of the reactant gases. Uneven distribution of the reactants can cause variations in current density, temperature, and water content over the area of a PEMFC, thus reducing the performance of PEMFC. By using Serpentine flow field channel, the performance is increased. Two types of serpentine flow field channels are implemented such as curved serpentine flow field channel and normal serpentine flow field channels. The result shows that curved serpentine flow field channel gives better current density and power density, thus increasing the performance of PEMFC.
