1. THE NEW ENERGY FUELS & STORAGE
Operation principles of alkaline, PEM (proton-exchange membrane) and solid oxide water electrolysis.
The overall reaction is H2O → H2 + 1/2O2. Oxygen evolution occurs at the anode, hydrogen evolves at the
cathode. The case of solid oxide electrolysis shown is that of an O2−-conducting electrolyte, with a
nickel/yttria-stabilized zirconia cathode and a lanthanum strontium manganite (LSM) anode
