Patent Number: 196793
Title: NANOENGINEERED MEMBRANE-ELECTRODE ASSEMBLY FOR HIGH-TEMPERATURE PROTON EXCHANGE MEMBRANE FUEL CELLS
Inventors: Besser; Ronald S.
Abstract: A membrane electrode assembly for a high-temperature proton-exchange membrane fuel cell includes a nano-engineered polymeric membrane between an anode and a cathode. The membrane is an electrical insulator, but permits that passage of protons through the membrane. The membrane has a plurality of blind pores therein, each blind pore having an electrically-conductive coating along its inner wall that is in electrical contact with the adjacent one of the anode or cathode. The electrically-conductive coating includes a catalyst, such as platinum, for promoting the liberation of a proton and an electron from a chemical molecule, such as hydrogen, and/or for promoting the combination of a proton, an electron and another molecule, such as oxygen, to form yet another molecule, such as water.
