Mechanical characterization of anion exchange membranes under controlled environmental conditions
MetadataShow full item record
While proton exchange membrane (PEM) fuel cells have been the focus of development in the past, anion exchange membranes (AEM) have the potential to dramatically lower the cost of fuel cells by utilizing non-noble catalysts and a variety of fuel sources. Although chemical degradation typically dominates membrane failure pathways in a fuel cell, mechanical breakdown due to humidity cycling is a common occurrence. This thesis aims to understand the mechanical properties of anion exchange membranes under fuel cell operating conditions. A humidity delivery system was developed for the TA Instruments ...
