Fuel cell bipolar plate

Product Overview
Hutchinson's bipolar plates are advanced components designed for fuel cells, playing a crucial role in electrical conduction and fluid management. Leveraging over 70 years of expertise in stamping, surface treatment, overmolding, and rubber-to-metal bonding, Hutchinson delivers bipolar plates manufactured from advanced materials that ensure high electrical conductivity and exceptional corrosion resistance.

Material and Functional Advantages
Our qualified rubbers exhibit very low hydrogen permeability, supporting optimal fuel cell chemistry with a low ion release rate. Surface coatings are engineered to meet demanding requirements for durability and conductivity. The overmolding process guarantees a perfect seal, meeting both functional and assembly needs, which enables cell pitch optimization and optimal Membrane Electrode Assembly (MEA) operation. Hutchinson's expertise in half-plate assembly by soldering and air testing ensures that the bipolar plates are compliant and ready for assembly.
