This report describes a new method for the fabrication of the "spun" electrode consisting of ionomer and catalyst supported on carbon. The obtained spun electrodes have a porosity and in-plane gas permeability more than ten times as large as an electrode made by conventional coating process. Spun electrodes are introduced to the membrane electrode assembly(MEA)for PEFC by direct fabrication on a membrane. The performance of MEAs was evaluated and it showed lower mass transfer loss than that using a coated cathode.
