Bipolar Plates

Hutchinson's bipolar plates for fuel cells guarantee optimal electrical conduction and efficient fluid management. We develop coatings which preserve conductivity and improve the corrosion resistance of the plates. Sealing and fluid distribution are ensured by rubber materials developed and validated for hydrogen applications, providing high reliability in demanding operating environments.
