Abstract
Polyaniline was used as a conductive matrix for depositing electrocata lyst (platinum) for the reduction of oxygen. Polyaniline was found to be a good conducting support for the platinum microparticles and by de positing platinum on the polymer, the active surface area of the elect rocatalyst was increased. However the rotating disk experiment also sh owed that there might be some limitation on the diffusion of oxygen th rough the polyaniline film.
