Electrolyser Coatings
Our Resillion™coatings for PTLs and bipolar plates power the efficiency, longevity and performance of PEM electrolysers.
James Cropper Advanced Materials specialises in the manufacture and development of materials for electrochemical, low-carbon technologies, such as PEM water electrolysis. The company produces a range of cost-effective coatings for electrolyser components which are proven to increase the stack efficiency, durability and lifetime of the system, reducing the long-term cost of green hydrogen production.

Coatings for Titanium Components
Enhancing the performance, efficiency and durability of PEM electrolysers
Our coatings are applied to a number of different titanium PEM electrolyser components to improve efficiency and lifetime. They reduce the voltage degradation rate of the electrolysers to just 3 μV/h over 10,000s hours, which equates to a 60% improvement compared to uncoated components. This significantly reduces the lifetime cost of hydrogen production.
A range of components can be coated using our Resillion process including porous transport layers (PTLs), cell separators, macro transport layers and bipolar and unipolar plates. The coating applied protects the parts from corrosion, reducing maintenance, as well as reducing and maintaining low contact resistance to maximise system efficiency.
