Interfacial constraints on water and proton transport across Nafion membranes
Original language description
Water and proton transport across a Nafion membrane are measured as functions of water activity and applied electric potential with a Polymer Electrolyte Hydrogen Pump (PEHP). Water and proton transport across the membrane must match water and proton transport entering and leaving the electrode/membrane/vapor three phase interfaces at the anode and cathode. At low applied electric potential proton and water fluxes are correlated. At moderate to high applied electric potential the proton current is constant, independent of applied electric potential, while the water transport increases with increasing electric potential. At high applied electric potential water and proton transport become uncoupled at the membrane interfaces; water is transported acrossthe membrane/vapor interface and protons are transported across the membrane/electrode interface. The applied electric potential drives electro-osmosis to redistribute the water in the membrane. Water redistribution is limited by the int
