Fuel cells and electrolyzers
In the future, electrolyzers will produce large amounts of green hydrogen using renewable energy. This hydrogen can then be used to power fuel cell trucks, planes or produce emission-free steel or fertilizer.


The membrane electrode assembly (MEA) is the heart of both technologies. Here is where the magic happens, either storing electricity by splitting water into hydrogen and oxygen or recovering that energy by reversing the process.

Our solution
The membrane electrode assembly (MEA) comprises more than 40 different materials and steps - one single change can make the difference. ionysis has all key competences to integrate latest material developments into your MEA with a strong focus on eco-friendly PFAS-free materials.


High complexity requires profound knowledge and high quality standards. As a university spin-off company based in Baden-Württemberg – the heart of Germanys automotive and automatization industry, we combine scientific excellence with highest standards in advanced manufacturing.
