From the late's, perfluorosulfonic acid (PFSAs) ionomers have dominated the PEM fuel cell industry as the membrane material of choice. The “gold. G. G. Scherer: Polymer Membranes for Fuel Cells. The best catalyst for oxygen reduction is platinum, but for oxygen evolution a mixture of RuOz and Ir02 is to. Proton-exchange membrane fuel cells (PEMFCs) are considered to be a promising technology for efficient power generation in the 21st century. The proton conductivity and cell performance of the polymeric membranes can be improved by high temperature treatment.

31 Mar It turns out that for conventional membranes and electrodes, as used in many fuel cells today, the limiting effect in the high current density region may be attributed to the dependence of the proton conductivity of the solid polymer electrolyte on its water content. Proton-exchange membrane fuel cells, also known as polymer electrolyte membrane (PEM) fuel cells (PEMFC), are a type of fuel cell being developed mainly for transport applications, as well as for stationary fuel-cell applications and portable fuel-cell applications. 26 Mar (polymer electrolyte membrane) responsible for internal proton transport Schematic representation of a proton exchange membrane fuel cell.
