This book describes the mechanism of membrane degradation and stabilization, as well as the search for stable membranes that can be used in alkaline fuel.
The proton exchange membrane (pem) fuel cell consists of a cathode, an anode and an electrolyte membrane. Hydrogen is oxidized at the anode and the oxygen is reduced at the cathode. Protons are transported from the anode to the cathode through the electrolyte membrane and the electrons are carried over an external circuit load.
