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.
