Fuel cell with segregated electrolyte distribution and method for making the same
Abstract
A method of making a fuel cell including the following steps: comprising: (a) mixing carbon nanotubes (CNT) with an initial dispersion, wherein the initial dispersion includes an ionomer; (b) heating and stirring the initial dispersion to form a CNT-ionomer composite suspension; (c) after forming the CNT-ionomer composite suspension, mixing the CNT-ionomer composite suspension with an electrode catalyst solution to form an electrode ink, wherein the electrode catalyst solution includes a carbon black powder and a catalyst supported by the carbon black powder; and (d) coating a proton exchange membrane with the electrode ink to form the fuel cell electrode.
