Abstract
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 ().
