Proton-Exchange Membrane

Basics

• A semi-permiable membrane that allows only for protons to flow through
• Used for Batteries, Fuel Cells, and Electrolysers
• Typically uses a floropolymer such as the proprietary Nafion

Possible Issues

• These are easy to find online etc, but making membranes from scratch may be very tricky, especially if using florine
• We should look into other membrane options

Notes From Eric

• I am not an expert on these, but I do think we should look into the possible supply chain issues of these
