Abstract
The invention is a method for making an improved membrane/electrode combination by at least partially coating at least a portion of a first face of a screen template with a plurality of catalytically active particles, where the substantially flat screen has the first face, a second face, and a plurality of openings passing therethrough which connect the first and the second faces of the screen. The openings occupy up to about 75% of the surface area of each face of the screen template. The coated face of the screen template is contacted with an ion exchange membrane. The catalytically active particles are transferred from the screen template to the membrane and the particles are bonded to the membrane.
