Synthesis and characterization of Br- and Cl- anion exchange membranesfor use in alkaline polymer electrolyte fuel cells
Contributor:Tansey, Emily; Herring, Andrew M.; Horan, James L.; Vandiver, Melissa
Proton exchange membrane (PEM) fuel cells utilize pure hydrogen fuel and platinum-based catalysts. Hydrogen has a relatively low energy density, so large-scale fuel storage is required to operate PEMs. Pt-based catalysts ...
Immobilization of heteropolyacids in PEM fuel cell membranes via copolymerization
Contributor:Jessop, Jeri D.; Herring, Andrew M.; Horan, James L.; Kuo, Mei-Chen
Nafion is the current standard by which PEM fuel cell membranes are measured. It is a PFSA (perfluoro sulfonic acid) polymer that is used to conduct ions such as protons. This material is only useful at low temperature ...
Addition of Carbon Black as a Conductive Support to Bimetallic Catalysts for Use in Anion Exchange Membrane Fuel Cells
Contributor:Wheatle, Bill; Ngan, Christine; Herring, Andrew M.; Greenlee, Lauren F.
The anion exchange membrane (AEM) fuel cell has the potential to become an important energy conversion technology. Unlike proton exchange membrane (PEM) fuel cells, AEMs do not use noble metal catalysts, allowing them to ...
Novel bimetallic catalysts for use in anion exchange membrane fuel cells
Contributor:Sather, Nicholas A.; Ham, James M.; Herring, Andrew M.; Greenlee, Lauren F.
Widespread implementation of current fuel cell technology is inhibited by the scarcity and price of the catalysts on both the anode and cathode. However, recent research suggests that Alkaline Anion Exchange Membrane Fuel ...
Heteropoly acid immobilization and crosslinking in a polymer electrolyte membrane for fuel cells
Contributor:Anyaeche, Ruth; Motz, Andrew; Kuo, Mei-Chen; Horan, James L.; Herring, Andrew M.
