Poly Vinylalcohol Zinc Oxide Nanocomposite Membranes for Fuel Cell Applications

Proton exchange membrane (PEM) fuel cells operate at comparatively low temperatures (<80ºC or <175ºF), offer quick start-up times, and require only hydrogen and oxygen to operate. PEM systems provide significant technical and cost advantages compared to competing solutions. Proton exchange membranes (PEMs) are the key components in fuel cell system. The researchers have focused to reach the proton exchange membrane with high proton conductivity, low electronic conductivity, low permeability to fuel, low electro osmotic drag coefficient, good chemical/thermal stability, good mechanical properties and low cost. These are classified into the “iron triangle� of performance, durability, and cost. Current PEMFC technology is based on expensive perflourinated proton-exchange membranes (PEMs) that operate effectively only under fully hydrated conditions. In requirement of the energy generation, small steps have been attempted by means of synthesizing the proton exchange membranes. Poly vinylalcohol and ZnO mixed matrix membranes were prepared in laboratory and measured for fuel cell applications.
