Polypyrrole (PPy) formation in the interior of a porous electrode by electropolymerization was considered to be impossible. When a concentrated pyrrole solution was soaked into a sintered-Ta electrode and electrolyzed in a pyrrole-free solution, PPy was formed in the interior. PPy occupied 70% of the inner space, and no defect was observed by SEM.
