Abstract
A fuel cell comprising an anode electrode, a cathode electrode, and a polymer electrolyte membrane disposed therebetween, wherein the fuel cell comprises a first layer of carbon nanotubes on at least one surface of the polymer electrolyte membrane, wherein substantially all of the carbon nanotubes are oriented in a planar direction with respect to the at least one surface of the polymer electrolyte membrane, and at least a portion of the carbon nanotubes comprise a catalyst material. The fuel cell may further comprise a second layer of carbon nanotubes on the first layer, wherein at least a portion of the carbon nanotubes in the second layer are oriented in an orthogonal direction with respect to the at least one surface of the polymer electrolyte membrane.
