Unlike those made from metal, ElectroPhen plates are chemically inert, do not corrode, will not poison fuel cell electrodes and are rugged enough to withstand the harshest environments. They are moulded, so do not need expensive machining or other finishing processes. And they are made using a simple, 2-stage, mix-and-mould manufacturing process that is far less complex, and therefore much less expensive, than those used to make other composite plates.

In short, ElectroPhen provides best-in-class performance for bipolar plates and end plates, at a uniquely affordable price.

Standard or full custom products to accelerate fuel cell development

Bac2 offers blank bi-polar and end plates for Proton Exchange Membrane (PEM) fuel cells as standard products. We also provide a rapid development service for custom plates with flow channels ready-moulded, so no further machining is necessary. We can fine-tune the composition of plates to match your precise requirements with respect to through-plane and in-plane conductivity, flexural strength and physical design.

Blank plates for development work are available in 300 x 200 x 3mm format, with conductivity that easily exceeds US Department of Energy specifications for use in automotive applications. Up to 100 plates can be supplied on 7-day delivery. Blank plates in additional sizes are under development and will be added to our product portfolio shortly. Please register to be updated with new product developments as they happen.
