Abstract:
1. A method of manufacturing a thermoplastic bipolar plate for a proton exchange membrane fuel cell, the method comprising: forming a resin mixture comprising a thermoplastic polymer, an electrically conductive filler material, and a solvent; rod coating the resin mixture onto a substrate to form a substantially flat film sheet having a first major surface and a second major surface opposite the first major surface; abrading a portion of at least one of the first major surface and the second major surface; after abrading, thermoforming the substantially flat film sheet with heat to form a thermoformed sheet; cutting the thermoformed sheet to form a first separator plate having a first size and a first shape and a second separator plate having a second size and a second shape; and joining the first separator plate and the second separator plate to thereby manufacture the thermoplastic bipolar plate so that the thermoplastic bipolar plate has an integral body.
