US Patent 7790331 - Fuel cell with nanowire film

Conductive nanowires have been used by Nanosys to create enhanced efficiency fuel cells. This patent from HP teaches a modification of such fuel cells using photoresist as a deposition liquid for the nanowires. Claim 1 reads:

1. A fuel cell, comprising:

an electrolyte substrate; and

a patterned film cathode established on the substrate, the patterned film including insoluble matter of an imaged photoresist having a plurality of nanowires dispersed therein, at least one of the plurality of nanowires contacting at least an other of the plurality of nanowires;

wherein the plurality of nanowires enhances catalytic activity and conductivity of the patterned film.
