Abstract
A membrane electrode assembly (MEA) with enhanced current density or power density is fabricated using high temperature (HT) proton exchange membrane (PEM). The MEA can be utilized in high temperature PEM fuel cell applications. More specifically, the MEA is modified with the addition of one or more of selected materials to its catalyst layer to enhance the rates of the fuel cell reactions and thus attain dramatic increases of the power output of the MEA in the fuel cell. The MEA has application to other electro-chemical devices, including an electrolyzer, a compressor, or a generator, purifier, and concentrator of hydrogen and oxygen using HT PEM MEAs.
