Understanding PEM Electrolyzers
What is a PEM Electrolyzer?
A PEM electrolyzer is a device that uses a solid polymer electrolyte to conduct protons from the anode to the cathode while separating hydrogen and oxygen. Unlike traditional alkaline electrolyzers, PEM units are more compact, operate at lower temperatures, and offer rapid start-up times.
How PEM Technology Works
- Anode Reaction: Water molecules are split into oxygen, protons, and electrons.
- Cathode Reaction: Protons and electrons recombine to form hydrogen gas.
- Electrolyte: A proton-conductive membrane that facilitates the reaction.
Key Applications in Industry
PEM electrolyzers are essential in:
- Renewable energy storage
- Fuel cell development
- Industrial hydrogen supply
- Laboratory and educational setups
