Bipolar Plates

Bipolar plates for fuel cells present a dilemma, they must be as strong as steel, light as a feather, conductive as copper, inert as gold and cheap as air. We are using thermoplastics with conductive fillers to make composite bipolar plates that approach the requirements of the ideal. We have the capacity to grind thermoplastics to micron particle sizes, mix with conductive particles, and compression mold the plates. Our laboratory can perform physical and electrical testing on the molded plates. Until a final flow field pattern is chosen, our CNC milling machine makes the pattern.
