Resillion™

Coating technology tuned to optimise hydrogen production

Developed for PEM electrolysers

Resillion™ coating technology that enhances conductivity, and protects electrolysers against corrosion and oxidation. Engineered for versatility and scalability, Resillion™ ensures optimal platinum efficiency, even on complex shapes, delivering unmatched performance and extended component life.

Resillion™ technology can be deployed across multiple components within the PEM electrolyser stack, including bi-polar and uni-polar plates, PTLs, sinters, and meshes. Follow the link to find out more about coating products from James Cropper.

What is Resillion™?

How it works

Resillion™ is a precious metal coating technology developed using a proprietary chemical deposition process that forms a uniform thin film with precise composition. It is specifically designed for electrolyser components and is highly compatible with various substrates, ensuring optimal efficiency and extended component lifespan.

Corrosion Resistance

Extended operational life. Electrolysers often operate in harsh, corrosive environments. Resillion™ coatings provide excellent corrosion resistance, protecting critical components from degradation.

Reduced Contact Resistance

Improved energy efficiency of the electrolyser system due to reduced contact resistance between components and enhanced electron flow.

High Adhesion Strength

The coating process ensures strong adhesion to the substrate, making the coatings durable and resistant to peeling or flaking.

Flexibility and Customisation

Our Resillion™ coatings can be tailored to specific requirements, offering flexibility in terms of thickness, composition, and properties to meet unique electrolyser stack requirements, whether that is complex shapes, large scale components or other properties.

Uniform Distribution

Due to the unique deposition of the technology, the Resillion™ process delivers a uniform distribution of coating. This uniformity is not limited by size or shape of the component, making it an optimal technology for use on parts that feature complex geometry or shapes.

Enhanced Conductivity

Better overall system performance and more efficient electrochemical reactions due to the improved electrical conductivity of the individually coated components.

Corrosion Resistance

Protection from degradation and extended operational life of the electrolyser due to the comprehensive protective layer from Resillion™.

Oxidation Resistance

Ensuring high performance of the electrolyser and preventing the loss of material integrity over time, Resillion™ delivers optimal protection from the consequences of oxidation.
