Next-generation membrane electrode assemblies for fuel cells and electrolyzers


Ionysis develops components for zero-emission fuel cells in heavy duty mobility and electrolyzers for hydrogen production.

Emissions from road traffic can be eliminated by usage of hydrogen fuel cells. Furthermore, fuel cells are the technology of choice for heavy-duty applications like ships, planes or trains. 

Electrolyzers will produce large amounts of green hydrogen using renewable energy. The hydrogen can then be used to power fuel cell trucks or produce emission-free steel or fertilizer.  

A polymer membrane with electrodes is the heart of both technologies.


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.
