Electrochemical Behaviour and Interfacial Contact Resistance of Ti-6Al-4V and SUS 316L plates with Potential Application as a Bipolar Plate in PEMFC / Nur Fawwaz Asri ...[et al.]

The main aim of this study is to investigate the corrosion of Ti-6Al-4V and SUS 316L plates as application at anode and cathode condition in PEMFC. The criteria for both current density (<1 μA cm−2) and interfacial contact resistance (<10 mΩ cm2) must meet the DOE’s 2020 technical targets. In...
