Producing renewable hydrogen by splitting water molecules into hydrogen and oxygen? This is the principle of electrolysis. But how does an electrolyzer work? Understand Proton Exchange Membrane (PEM) electrolysis, in just 94 seconds. | Air Liquide

Hydrogen = pure energy! 💪 Every second, 600 million tonnes of hydrogen are melted in the center of the sun ☀️ to become pure energy. But how to produce hydrogen from water 💧....since collecting hydrogen from the sun might be a little bit tricky!? 🤔 | OMV

Reversible PEM Fuel Cell: this blue unit contains a Proton Exchange Membrane and platinum catalyst that enables an electrochemical reaction to generate electricity from combining hydrogen and oxygen into water (a hydrogen fuel cell), and if a current is supplied (say with two AA batteries) the process runs in reverse with the PEM assembly converting water in to hydrogen and oxygen. This kit uses little “diving bell” structures to capture the gasses that can then be used as fuel to power a motor.
