Design and Characterization of Nonwoven Fabrics for Gas Diffusion Layer in Polymer Electrolyte Membrane Fuel Cell

Abstract

The aim of this research is to develop and evaluate materials for polymer electrolyte membrane fuel cells. Gas diffusion layer (GDL) is a part of membrane electrode assembly (MEA) that is the locomotive of polymer electrolyte membrane fuel cell (PEMFC). In this work, a PEMFC is built to study the MEA’s behavior during operation. New gas diffusion layer structures are manufactured and their characterizations are done by compression-resistance test. The strength and resistance values of the new materials are comparable to those of the commercial materials tested
