Membrane

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. These polymer membranes that conduct proton through the membrane but are reasonably impermeable to the gases, serve as solid electrolytes (vs. liquid electrolyte) for variety of electrochemical applications, and are commonly known as Proton Exchange Membrane and/or Polymer Electrolyte Membranes (PEM). These membranes have been identified as one of the key components for various consumer related applications for fuel cells, e.g. automobiles, back-up power, portable power etc. Due to its application for many consumer markets, the technology keeps on evolving to make these membranes suitable for longer duration, and even high temperature operations.
