Proton Exchange Membranes (PEM) are a thin polymer electrolyte membrane. It's used in fuel cells and electrolyzers to conduct positively charged hydrogen ions or protons, producing water and hydrogen as byproducts. The PEM separates the anode from the cathode. This allows hydrogen ions to flow from the anode to the cathode through the membrane. Electrons provide an electrical current as they flow through an external circuit.
PEM is widely used in transportation, stationary power generation, and portable power applications.
Titanium offers optimal performance in highly oxygenated PEM environments. Its characteristics impart electrical potential, improved oxidation and corrosion resistance, and more. Plus, it's proven history of stability makes it the medium of choice.
Acidic environments like PEM are notorious for generating a corrosive buildup. Over time, this oxide layer leads to the slow degradation of materials. This is where coated titanium is enabled to shine. By adding a thin coating of platinum, the titanium medium is protected from any possible insulative effects.
