Transport properties of anion exchange membranes for fuel cell applications
MetadataShow full item record
Low temperature fuel cells are emerging technology for efficient energy conversions. Polymer membrane electrolytes used in the fuel cell devices should be highly conductive, chemically and mechanically stable under extreme operating conditions of temperature and humidity, and cost effective. Although proton exchange membranes (PEM), such as Nafion® are highly conductive and chemically and mechanically stable, PEMs are not widely used in fuel cells due to the higher cost of fluoropolymers and the platinum metal catalysts. Anion exchange membranes (AEM) offer lower cost of both polymers and metal ...
