英文摘要	forming a coating on metals by surface treatment is a good way to get high performance bipolar plate of proton exchange membrane fuel cell (pemfc). in our research, ag-polytetrafluoroethylene (ptfe) composite film was electrodeposited with silver-gilt solution of nicotinic acid by a bi-pulse electroplating power supply on 316l stainless steel bipolar plate of pemfc. surface topography, contact angle, interfacial conductivity and corrosion resistance of the bipolar plate samples were investigated. results showed that the defects on the ag-ptfe composite coating are greatly reduced compared with those on the pure ag coating fabricated under the same condition; and the contact angle of the ag-ptfe composite coating with water is 114 degrees, which is much bigger than that of the pure ag coating (73 degrees). in addition, the interfacial contact resistance of the composite coating stays as low as the pure ag coating; and the bipolar plate sample with composite coating shows a close corrosion resistance to the pure ag coating sample in potentiodynamic and potentiostatic tests. coated 316l stainless steel plate with ag-ptfe composite coating exhibits well hydrophobic characteristic, less defects, high interfacial conductivity and good corrosion resistance, which shows a great potential of the application in pemfc. crown copyright (c) 2008 published by elsevier b.v. all rights reserved.
