We have studied interfaces between conducting polypyrrole and aqueous and solid polymer electrolytes. Polypyrrole is porous to solvent and electrolyte ions but not to solid polymer electrolytes. Contrasting the two interfaces shows unambiguously that the porosity, and consequently large actual surface area, is responsible for the observed rapid rate of charge transfer to ionic species in solution
