Novel coatings deposited by modulated pulsed power magnetron sputtering for PEM fuel cell and electrolyser bipolar plates
Bipolar plates (BPP) are crucial components in these devices. BPPs are exposed to acidic environment, but also must withstand high overvoltage in the anodic side (2 V) and cathodic side (1.4 V) of the PEM electrolyser and fuel cell, respectively.
In this study, different multilayer coatings deposited by modulated pulsed power magnetron sputtering (MPPMS) on titanium and stainless steel BPP are investigated. The coatings must be high corrosion resistant and electrically conductive in PEM environment.
Ex-situ electrochemical tests and interfacial contact resistance (ICR) measurements were conducted in PEM environment to evaluate the performance of these coatings for enhanced durability of BPP.
