Abstract
A proton-exchange-membrane fuel cell bipolar plate includes a metal substrate having a bulk portion and a surface portion including an anticorrosive, conductive binary phosphide material having a formula (I): AxPy (I), where A is an alkali metal, alkaline earth metal, transition metal, post-transition metal, or metalloid, x, y is each a number independently selected from 1 to 15, and the binary phosphide material is configured to impart anticorrosive and conductive properties to the metal substrate.
