DuraC: The automotive fuel cell industry's most-wanted coating. Advancing toward qualification.
For years, the automotive fuel cell stack industry has been searching for the same thing: a carbon-based bipolar plate coating with low contact resistance, long service life, and a cost structure compatible with high-volume OEM production. DuraC is that coating. TreadStone's patented DuraC technology is a thin-layer carbon coating (20–50 μm) that bonds directly to metal surfaces, creating dense electrical contact points with exceptionally low resistance — at the cost per unit that automotive programs demand. DuraC is completing performance validation on titanium electrode substrates in flow battery applications, with test data confirming it meets the full performance specification for commercial flow battery deployment. Long-term durability studies are progressing. DuraC's electrolyte-agnostic chemistry and low material cost make it a strong candidate for flow battery electrode coating programs at scale. Engineering evaluation samples are available through TreadStone's qualification process. Our team is ready to support your material data packages and supplier qualification requirements. The automotive fuel cell market is scaling — contact TreadStone to discuss your program timeline.
