A nanostructured electrode for a polymer electrolyte fuel cell, a manufacturing method thereof, and a fuel cell including the nanostructured electrode are provided. The nanostructured electrode includes: a three-dimensional nanostructure including a nanoporous aerogel and an ionomer surrounding the surface of the aerogel; and a catalyst dispersed in the three-dimensional nanostructure. The electrode can obtain excellent current density and power density even with a relatively small amount of catalyst by having improved catalyst performance due to nanostructuring of an ionomer, uniform catalyst dispersion and increased catalyst utilization ratio, can also obtain a price reduction effect through a decrease in the amount of catalyst used, and is excellent in the mass transfer efficiency and low humidification performance.

Nanostructured electrode for polymer electrolyte membrane fuel cell, and manufacturing method therefor

Provided are a polymer electrode membrane including a porous support including a web of nanofibers of a first hydrocarbon-based ion conductor that are arranged irregularly and discontinuously; and a second hydrocarbon-based ion conductor filling the pores of the porous support, the first hydrocarbon-based ion conductor being a product obtained by eliminating at least a portion of the protective groups (Y) in a precursor of the first hydrocarbon-based ion conductor represented by Formula (1), a method for producing the polymer electrolyte membrane, and a membrane electrode assembly including the polymer electrolyte membrane: wherein m, p, q, M, M', X and Y respectively have the same meanings as defined in the specification.
