MIXED FEED DIRECT METHANOL FUEL CELL MODIFIED BY SEMIPERMEABLE MEMBRANE FOR CATALYST LAYER

摘要

Electrodes are used in fuel cells for generating electricity from a mixed feed, where the mixed feed comprises a fuel portion and an oxidation portion. Fuel cells incorporating the electrodes and a method of fabricating the fuel cells are described. In some embodiments, the electrodes comprise a barrier layer (120, 160) having first and second sides, permeable to one of the fuel portion and oxidant portions of the mixed feed, a catalyst layer (130, 150) formed on the first side of the barrier layer, and the reactant distribution layer (1 10, 170), formed on the second side of the barrier layer.
