Development of Porous Polypyrrole Electrode for Fuel Cell Applications

Abstract:

One method of increasing number of reaction sites was by the introduction of a porous structure into the electrodes to provide a high surface area for catalyst deposition. This work focused on the development of a method for the fabrication of a porous polypyrrole electrode; a mixture of two monomers (i.e. pyrrole and methylene blue) was simultaneously electropolymerised and one of which was selectively removed from the composite film by solvent extraction. The porous polypyrrole had a suitably porous structure whilst maintaining excellent electrical properties. The application of this novel material to miniaturized fuel cells was shown to have improved power density of 2-fold and 3-fold higher than bulk polypyrrole and bare gold electrodes respectively.
