| Summary: | 碩士 === 國立虎尾科技大學 === 光電與材料科技研究所 === 96 === In this study, the corrosion behavior of electroless Ni, Au and Ag plating
on AISI 304 stainless steel is investigated in simulated polymer electrolyte membrane fuel cell (PEMFC) environment. The main purposes are to offer fundamental information for the development of metal bipolar plates in PEMFC, and to obtain a deeper understanding of the electrochemical corrosion characteristics for electroless plating systems. This study addresses the corrosion resistance characteristics of electroless plating on AISI 304 stainless steel for PEMFC bipolar plate applications. Corrosion properties of this material were studied by using potentiodynamic and potentiostatic tests. Electroless Ag plating on AISI 304 stainless steel showed excellent corrosion resistance (corrosion current density, 1.876nA/cm2) in anodic and cathodic atmospheres under potentiostatic conditions. Moreover, electroless Ag plating on AISI 304 stainless steel showed lower the interfacial contact resistance of as compared to Ni and Au electroless plated on AISI 304 stainless steel, and respectively.
