Innovate your electrolyser component(s) at the Faraday Lab
A lack of clear insight into the real-world performance and reliability of electrolyser components can slow down innovation and implementation. We help start-ups, SMEs, industrial partners and RTOs test and validate their electrolyser components, while supporting further development through R&D. This takes place at TNO’s Faraday Lab.
TNO’s Faraday Lab is one of Europe’s leading research facilities for hydrogen electrolysers, offering extensive experimental infrastructure for the evaluation of electrolyser components and cells.
Our laboratory combines single-cell and parallel PEM test setups, alkaline and AEM platforms, and advanced SOE facilities capable of testing the largest cells currently available, including under high-pressure conditions. This allows us to place individual results within a broader technological and performance context.
What we analyse in our standard R&D assessments
Our standard R&D assessment establishes a performance baseline and identifies initial indications of limitations, safety issues or degradation through in-situ characterisation and pressure testing.
When the standard R&D assessment reveals specific questions or bottlenecks, we offer advanced analytical techniques, including ex-situ testing, to investigate the underlying mechanisms in greater detail.

What you provide
- You have an electrolyser component or coating that you want to test, measure in situ, or validate under realistic operating conditions.
- This may be for independent validation or for a specific application.
What you receive
- You receive raw experimental data and clear graphical outputs, together with an initial assessment of your component’s performance and behaviour.
- Our experts place your results into context and provide an initial independent evaluation based on our expertise and broad overview of the electrolyser field, identifying potential bottlenecks and limitations in performance or behaviour.
PEM R&D Assessments
Complementary assessments
Based on this assessment, we offer the possibility to proceed with an in-depth analysis focused on result interpretation, underlying mechanisms, and targeted next steps for further optimisation and scale-up.
