Membranes in order for a pem fuel cell to operate, a proton exchange membrane is needed that will carry the hydrogen ions, proton, from the anode to the cathode without passing the electrons that were removed from the hydrogen atoms.
This special issue from international journal of green energy is devoted to recent progress in the development of pem fuel cell.
At the cathode, another catalyst causes hydrogen ions, electrons, and oxygen to react, forming water. Fuel cells are classified by the type of electrolyte they use and by the difference in startup time ranging from 1 second for proton exchange membrane fuel cells (pem fuel cells, or pemfc) to 10 minutes for solid oxide fuel cells (sofc).
