Abstract	:	With the cathodic hydrogenation and isomerization of unsaturated hydrocarbonsin a Polymer Electrolyte Fuel Cell, we wanted to investigate an alternative heterogeneouscathodic process to perform acid catalyzed reactions. In this process, the catalytic activityand selectivity of the catalyst/solid electrolyte interface could be tuned by controlling theproton spillover via an electrical potential. Acidic metal supports. such as zeolites orc l a s function through their ability to release and accept protons. Similarly, the use ofproton solid electrolyte membranes, such as Nafion allows the electromigration ofprotons from the fuel cell anode to the corresponding cathode. Of various fuel cellsystems considered, the polymer electrolyte fuel cells using Nafion as the solidelectrolyte seemed to be the most suitable system because the acidic properties of theNafion.The products from the hydrogenation and isomerization reactions of ZJ Dimethyl-i -Butene (2JDMlBE) were 2JDimethylbutane (2,3DMBA) and 2.3Dixnethyl-2-Butene(2.3DM2BE) respectively. The Non-Faradaic Modification of Catalytic activity(NEMC A) or the electrochemical activation of the catal yst/Nafion interface enhanced thecatalytic rate of the isomerization reaction. The isomerization of UDimethyi-1-buteneformed 2,3Dimethylbutane as the product fiom the skeleton rearrangement....-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
