Catalytic Performance Enhancement by Low Temperature Plasma Treatment

Miley G.H., Srivastava S.N., Chen G., UiUC/NPL Associates, US

Polymer Electrolyte Membrane (PEM) fuel cell electrocatalysts are composed of noble metals (e.g. platinum), which are scarce and expensive. A simple plasma-surface modification method is described to increase the performance of PEM fuel cell catalytic [...]

Enhanced fuel cell performance with modified Nafion® membranes

Krishnan L., Yeager G., Clark K., Kerr J., Soloveichik G., Miebach T., GE Global Research, US

The interaction of Nafion® 212 membrane with a carbocyclic fuel, decalin was studied. Decalin treatment of N212 improved vapor sorption and membrane conductivity. In addition a substantial increase of peak power in a H2/Air fuel [...]

Electrical Potential Distribution in Nanopores

Gillespie A.R., Paul R., Paddison S.J., Motorola, US

The study of the transport of ionic species through nanopores is a subject of wide interest covering several diverse fields such as biophysics, electrochemistry and polymer science. While, during recent decades, considerable advances have been [...]

Modeling Water Uptake of Proton Exchange Membranes

Berg P., Promislow K., Simon Fraser University, CA

Water content in Nafion membranes of proton exchange membranes (PEM) is crucial to its functionality. The adsorption of liquid water occurs on a time scale of seconds, while the desorption (drying) time scale is on [...]

Computational Modelling and Structural Studies of Perfluoro Sulfonate Ionomer Membranes

Elliott J.A., University of Cambridge, UK

Perfluoro sulfonate ionomer membranes (PIMs) consist of a Teflon (PTFE) backbone with sulfonic acid groups periodically substituted along the chain, and are of great commercial interest due to their peculiar ion transport properties. In particular, [...]
