The Membrane Electrode Assembly MEA is the core component of a fuel cell that helps produce the electrochemical reaction needed to separate electrons. On the anode side of the MEA, a fuel hydrogen, methanol etc. diffuses through the membrane and is met on the cathode end by an oxidant oxygen or air which bonds with the fuel and receives the electrons that were separated from the fuel. Catalysts on each side enable reactions and the membrane allows protons to pass through while keeping the ... Read more
