James Cropper and National Physical Laboratory collaborate to advance corrosion resistance research for PEM electrolysers

James Cropper Advanced Materials (formally TFP Hydrogen Products) is working with the National Physical Laboratory (NPL) to undertake advanced research into the corrosion resistance of components for proton exchange membrane water electrolysers (PEMWE), a critical technology for green hydrogen production. 

TiCORR Project: Mapping Corrosion Resistance in PEM Electrolyser Components

The project, “Corrosion Resistance Mapping of Coated Titanium Components for PEM Water Electrolysers (TiCORR)” will investigate how the microscopic properties of platinum coatings, such as surface finish and the presence of micro- and nanoscale flaws, can impact the long-term durability and efficiency of electrolyser components. By understanding how localised variations affect corrosion, the research will provide insights that can inform component design, improve manufacturing and reduce maintenance costs, helping the hydrogen industry deliver longer-lasting, higher-performance PEM electrolysers.

“ Our specialist coatings are already delivering step changes in PEM electrolyser performance, significantly improving efficiency, durability and system lifespan while reducing operational costs and enhancing asset value. At present, there is no standard corrosion measurement technique for these components. This collaboration with NPL presents a valuable opportunity to deepen our understanding and drive further innovation in green hydrogen technologies. ”

The TiCORR project addresses a key technical challenge: how localised variations in platinum coatings, such as differences in thickness or surface appearance, affect corrosion resistance at a fine scale. While corrosion behaviour can be assessed reliably across larger surfaces, much less is known about how small inhomogeneities within coatings contribute to degradation. 

Micro-scale Analysis to Optimise Coating Performance

To investigate this, James Cropper will work in partnership with NPL to conduct detailed, micro-scale analysis using advanced techniques: 

Scanning electrochemical microscopy (SECM) will be used to map localised electrochemical activity, providing insight into how corrosion initiates and develops.

High-resolution scanning electron microscopy (SEM) and 3D optical microscopy will be used to investigate surface morphological changes resulting from corrosion.

The research will be led by Dr Sameera Mitta, Scientist at James Cropper, who will oversee the technical execution and collaboration with NPL.  

By understanding localised corrosion behaviour and its relationship with coating inhomogeneities, the findings will enable researchers to pinpoint specific regions where corrosion initiates and progresses, paving the way for the optimisation of coating technologies. This will ensure that the highest level of corrosion resistance is achieved uniformly across the entire surface of the component.

“ This is a great opportunity to leverage NPL’s capability in corrosion science and materials characterisation to address a challenging measurement need. NPL has a rich history in developing mechanistic understanding of localised corrosion processes in industry, while also undertaking a research programme in electrochemical hydrogen technologies, so we are well-positioned to tackle this problem. ”
