| Research Abstract |
Yttria-stabilized zirconia (YSZ) was polarized into electrets and oxygen reduction reaction on Pt-C composite catalyst was measured using the YSZ electrets as a catalyst carrier in order to confirm an influence of static electrical field of the YSZ electrets on the catalytic activity. Judged by the kinetic current (Ik) estimated by the oxygen reduction current measurements, the surface of YSZ electret polarized on negative electrode appeared to have a potential to activate the catalytic reaction of oxygen reduction.
