State-of-the-art metal bipolar plate coating

The Ceramic MaxPhase™ coating exceeds both performance and cost targets set up by the US Department of Energy for metal bipolar plates. The coating is proven state-of-the-art for proton exchange membrane fuel cells (PEMFC), running on hydrogen or reformate gas, and also for direct methanol fuel cells (DMFC), in terms of electrical contact resistance, corrosion resistance, and durability.

Impact Coatings works closely with customers and industry partners to build supply chains for PEMFC and DMFC metal bipolar plates. We also participate in development projects for other fuel cell technologies, including high temperature PEMFC.

Ceramic MaxPhase™

Ceramic MaxPhase was developed by Impact Coatings and qualified in cooperation with leading fuel cell manufacturers. The coating creates a protective surface with low electrical contact resistance on the metal bipolar plate, optimized for the corrosive environment inside the fuel cell. Deposition is made on pre-formed bipolar plates for maximum performance and lifetime of the fuel cell stack.

Ceramic MaxPhase consists only of safe and low-cost materials: transition metals, group-A elements, and nitrogen and/or carbon.

Coating service and volume production

Impact Coatings supports customers with coating solutions all the way, from initial material testing and stack development, through prototyping, and supply chain build-up for high volume production.

We provide short turn-around coating services of Ceramic MaxPhase on metal bipolar plates from our production facility in Sweden. This allows our customers to quickly perform tests, and coat plates for prototyping at a low investment.

When volumes increase we can supply the turn-key InlineCoater™ 500 PVD production equipment and source material for Ceramic MaxPhase, and provide service worldwide.
