Meta- and para-linked homopolymers bearing 3-methylphenyl (Me) pendent groups were postsulfonated to create sulfonated poly(ether ether ketone ketone) (SPEEKK) backbone isomers, which are referred to as Me- p -SPEEKK and Me- m -SPEEKK. Their thermal

The conversion of methane to methanol in low temperature alkaline flow cells is studied. The mechanism of oxygen insertion without breaking the C-H bond for methane activation is examined with both hydroxide and carbonate oxygen donors. The effective

A new method to reduce methanol crossover in fuel cells is presented. This approach relies on coating an anode gas diffusion layer with poly(3,4-ethylenedioxythiophene), which is achieved by an electropolymerization method. Methanol permeability thro

Hydrogen fuel cell performance of sulfonated diels alder poly(phenylene) (SDAPP) with IECs ≥ 1.8 meq g −1 is comparable to Nafion 212 under fully humidified conditions at 80 °C. However, as relative humidity is reduced, performance loss is subst

We have successfully immobilized several HPA on carbons using covalent attachment. The morphology of these materials is still under investigation, but the hybrid HPA carbons can be used to stabilize nano-Pt particles. The fuel cell performance is not

The use of heteropoly acids (HPAs) in PEM fuel cell anode catalyst layers was studied. To compare the doped electrodes with a control electrode in a meaningful way membrane electrode assemblies (MEAs) were prepared with two 1/2 anodes, one the undope
