Develpment of novel Proton Exchange membranes (PEM)
StatisticsView Usage Statistics
Proton Exchange Membrane (PEM) was developed for the use in PEM fuel cells. Membranes were cast from various polymers and composite membranes were prepared with heteropoly acid (HPA) particles. Studies were conducted on various polymers and their possible application in fuel cells. Proton conductivity and other characterization techniques were carried out for the polymeric membranes. For high temperature operation of fuel cells novel high temperature stable polymers were developed and characterized. It was found that the new polymer based systems increased the overall performance of the system. Single membrane tests were carried out to study the performance of the fuel cell.
