## Abstract A novel method is proposed to fabricate the active catalytic layers of proton exchange membrane fuel cells (PEMFC). A plasma sputtering technique is used to deposit a porous columnar carbon film (column diameter of 20βnm) followed by the catalyst (platinum) deposition directly on the pr
A d.c. triode sputtering gun has been used to produce thin carbon films by sputtering from a graphite target in argon at two different powers. The films were produced on glass, aluminum foil, and single crystal sodium chloride substrates. The films were studied by X-ray photoelectron spectroscopy, A
