AI Overview
A cathode catalyst, primarily using platinum (Pt) or platinum-based alloys, facilitates the Oxygen Reduction Reaction (ORR) in fuel cells and PEM electrolyzers, speeding up reactions to turn oxygen into water or electricity. These catalysts are designed as porous, high-surface-area structures to maximize efficiency, often employing precious metals such as platinum and palladium for durability.

What are catalytic agents used for?
During a chemical reaction, the bonds between the atoms in molecules are broken, rearranged, and rebuilt, recombining the atoms into new molecules. Catalysts make this process more efficient by lowering the activation energy, which is the energy barrier that must be surmounted for a chemical reaction to occur.Apr 17, 2026
