ABSTRACT:
A polymer electrolyte and a fuel cell employing the polymer electrolyte are provided. The polymer electrolyte includes: an ionic conductive polymer membrane; a porous support having nano-sized pores; and inorganic conductive nano-particles including an ionic conductive material impregnated into the porous support, wherein the inorganic conductive nano-particles are impregnated into microchannels formed by aggregation of polar portions of the ionic conductive polymer membrane, and/or between polymer backbones of the ionic conductive polymer membrane.
