Executive Summary 

Proton Electrolyte Membrane (PEM) fuel cells are a promising renewable energy technology, particularly for use in automobiles due to the lightweight design of the PEM fuel cell. A major challenge faced by this technology, however, is the expense of the platinum catalyst now most commonly used and its deactivation by carbon monoxide from the fuel stream.

One potential solution is to replace platinum with an alternative catalyst material. Halogenated graphene is one such recently identified promising catalyst. The properties of this material were examined using Density Functional Theory, and predictions made concerning the suitability of halogenated graphene for use catalyzing the oxygen reduction reaction in the PEM. Furthermore, the NMR spectrums of several of kinds of halogenated graphene materials are predicted.
