Abstract
A polymer electrolyte fuel cell (PEFC), comprises a first electrode and a second electrode, wherein the first electrode includes a coaxial nanowire electrode. In some embodiments, the coaxial nanowire electrode comprises a plurality of ionomer nanowires, and a catalyst coating that coats at least part of the ionomer nanowires. Moreover, in some embodiments, a nanowire of the plurality of ionomer nanowires and a section of the catalyst coating that coats the nanowire form two coaxial cylinders.
