Oxidation of 2-propanol in alkaline electrolytes using platinum and ruthenium-based catalysts: prototype fuel cells and electrokinetics studies
DownloadFall 2011
Markiewicz, Matthew Eugene Paul
Alcohols are an attractive alternative to hydrogen fuel in fuel cells. They are energy dense, easy to store, transport, and they are readily available. Alkaline fuel cells have several kinetic advantages over acidic fuel cells, but they are sensitive to carbon dioxide. The fuel most studied in...

Computer modeling is critical for catalyst layer (CL) design in polymer electrolyte membrane fuel cells. Water-filled and ionomer-filled agglomerate models have been suggested as representations of the CL microstructure. In this thesis, improved water-filled and ionomer-filled agglomerate models...

Experimental and theoretical investigation of mass transport in porous media of a PEM fuel cell
DownloadFall 2011
Porous media is an integral part of polymer electrolyte fuel cell (PEMFC) electrodes. In this study, an experimental setup is presented to investigate convective and diffusive mass transport in porous media of fuel cell electrodes. A new theoretical model was developed in order to correct for...
