Take control of your production
Impact Coatings has been supplying customers with hydrogen coating solutions for more than a decade. Our PVD technology offers clean coating processes and allows the production of high-performing fuel cell and electrolyzer coatings optimized for increased durability.
Our delivery models are flexible to meet the production needs in all development stages. We support customers from test and verification stages to pre-series volumes, up to full volume production in our Coating Service Centers. We can also support customers with managed services or offer an in-house production system perfectly matched to the customer’s application.
This proven service and system delivery model supports the hydrogen industry to scale up with maximum control in each production phase.
Electrolyzer stack components are a vital part of generating green hydrogen. During the electrolysis process, the components are subjected to harsh environments and require embrittlement protection, extreme corrosion resistance, and low contact resistance to perform well.
PEM electrolyzers have significant advantages to alkaline-based technology – such as a small footprint, high power density, fast response time, and the use of pure water instead of corrosive alkaline solutions. PEM electrolyzers, however, use several titanium components that make the stack susceptible to oxidation and require a thin layer of metal coating for durability and performance.
Electrolyzer Coating Solutions
Impact Coatings’ Water Electrolyzer Coatings provide outstanding corrosion resistance, low contact resistance and excellent adhesion for highest possible durability and performance. The coatings can be precisely controlled and adapted utilizing one or several coating materials to optimize anode and cathode properties.
For increased stack performance and lifespan, the metal bipolar plates in a proton exchange membrane fuel cell stack needs protection with a conductive and stable FC coating.
Without a robust, high-performing FC coating, the bipolar plates will start to leach ions into the stack. This harms the stack membrane’s functionality, which leads to reduced performance, and in the end stack failure.
To mitigate hydrogen starvation and maintain the highest possible performance during the entire stack lifetime, the FC coating should be able to withstand extreme potential spikes and temperatures without degradation.
Next Generation Premium FC Coating | Heavy Duty Applications
With Impact Coatings’ robust, premium, next generation FC coating, insignificant amounts of iron, chromium, nickel and aluminum are released at potentials up to 1.6 V. Adhesion and conductivity with a stable and low interfacial contact resistance will therefore be maintained throughout the entire lifetime of the stack.
Ceramic MAXPHASE | Mid-End Applications
The Ceramic MAXPHASE™ coating for LT-PEMFC was introduced in 2012 and was selected for the first production fuel cell car application in 2015.
The Ceramic MAXPHASE™ coating for LT-PEM metal plates provides enhanced properties, such as lowered contact resistance and corrosion protection for increased durability and high performance. It’s a unique, ceramic coating technology developed with cost-efficiency and reliability in mind.
Verified by ZBT
Ceramic MAXPHASE™ has been verified to be on par with gold coatings of metal plates in an LT-PEM fuel cell in terms of current density and degradation. The test was performed by the independent German research institute ZBT (Zentrum für BrennstoffzellenTechnik GmbH).

We continue to work closely together with our customers for improved and new coating solutions. This includes coatings for LT-PEMFC, but also for other fuel cell applications and technology for hydrogen production. For more information, contact us today.
Coating Services and Class-Leading PVD Coating Systems
In addition to highly efficient coating materials, Impact Coatings supports customers with production solutions all the way from pilot or pre-series production to full scale volume manufacturing.
At our facility in Sweden we provide a full in-house coating operation for metal bipolar plates as well as other non-fuel cell related coating production. The coating service typically supports customers during prototype and pilot production phases and is utilized by plate and stack manufacturers globally.
When customer volumes increase, we supply the class-leading INLINECOATER™ coating equipment optimized for fuel cell plates and prepared for integration in automated manufacturing lines.
