An Ultrathin Self-Humidifying Membrane for PEM Fuel Cell Application:  Fabrication, Characterization, and Experimental Analysis

An ultrathin poly(tetrafluoroethylene) (PTFE)-reinforced multilayer self-humidifying composite membrane (20 μm, thick) is developed. The membrane is composed of Nafion-impregnated porous PTFE composite as the central layer, and SiO2 supported nanosized Pt particles (Pt−SiO2) imbedded into the Nafion...
