Since 2001, Porvair has been developing proprietary bi-polar plates in conjunction with the U.S. Department of Energy.

A fully molded, carbon – graphite Bipolar Plate has now been launched, for use in PEM fuel cells.

This plate, which is based upon work licensed from Oak Ridge National Labs, has all of the superior properties found in machined graphite plates, but the cost structure of resin composite molded products.

The plate is lightweight, which can provide full stack weight savings of up to 36 lbs., and is all carbon, which eliminates the chance for contamination, and improves durability.

Outstanding electrical properties assure excellent cell performance.

Moldability of the product is excellent, with web thickness of less than 10 mils available, and the product can be molded with intricate and demanding flow fields.

Porvair Fuel Cell Technologies has developed the fully molded carbon – graphite Bipolar Plate to meet the needs of the fuel cell industry for high quality products, which can be produced at low cost.
