The state of the art proton exchange membrane fuel cells for clean energy

Abstract

This overview paper gives a snapshot of the challenges associated with a proton exchange membrane fuel cell (PEMFC). Different materials such as carbon nanotubes (CNTs) have been synthesised and studied to improve fuel cell performance. The utilization of CNTs properties on Pt catalyst and Nafion membrane promises the state of the art PEMFC. Thermo-mechanical properties and methanol permeability of Nafion membranes were greatly improved by incorporation of only 1 wt% of CNTs.
