A polymer electrolyte membrane fuel cell (PEMFC) which uses stainless steel as a bipolar plate has many advantages over conventional machined graphite. Austenitic stainless steel 316L is a traditional candidate for metal bipolar plates. During a long operation time, metal oxide formation leads to contact resistance, and metal dissolution can cause contamination of the membrane electrode assembly (MEA). A pure Carbon was coated on the surface of Stainless steel and provided a good anticorrosion layer. The carbon film has a low area specific resistance compared to the composite coating because it has a high surface conductivity. In addition, The ICR between the carbon-coated SS316 and the carbon paper is 1100-3000 mΩ-cm2 under compaction forces between 20 and 280 N/cm2. The carbon-coated SS316L shows good corrosion resistance in the simulated PEMFC environment. After 4000hrs of testing time, the power density of a single cell was less than 1% decline. Therefore, the carbon-coated SS316L has an excellent durability property.
