To form an ionomer-based catalytic layer on a porous substrate, a heat source () is used to dry an ionomer-containing spray () so that it does not substantially liquid flow on the substrate (). The ionomer spray () may contain a catalyst. A spray () of mixed material for forming the catalytic layer is entrained by a gas stream and is heated and directed to a substrate surface (). For hydrogen/oxygen fuel cells, catalytic material is incorporated into the proton-conducting membrane () to convert diffusing oxygen and hydrogen to water to reduce potential loss at the electrodes and maintain hydration of the proton-conducting membrane ().

Fuel cell membranes and catalytic layers

Tunable capacitors () have a dielectric material () between electrodes, which dielectric material comprises an insulating material () and electrically conductive material, () e.g., conductive nanoparticulates, dispersed therein. In certain cases, enhanced tune-ability is achieved when the dielectric material comprises elongated nanoparticulates (). Further enhanced tune-ability may be achieved by aligning elongated particulates in an electrode-to-electrode direction. Nanoparticulates may be produced by heating passivated nanoparticulates. Passivated nanoparticulates may be covalently bound within a polymeric matrix. High bias potential device structures can be formed with preferential mobilities.
