Polymerelektrolytmembran-Brennstoffzelle

DE 19951687 A UPAB: 20010615 NOVELTY - Fuel cell has several reaction chambers separated by a polymer electrolyte membrane with electrical conductors (11a, 11b) arranged in the chambers. The cell is formed from a bundle of hollow fibers (10), especially capillary hollow fibers. The electrical conductors of the same polarity are provided inside and outside of the hollow fibers and are connected to each other forming an anode and a cathode of the cell. DETAILED DESCRIPTION - The hollow fibers are preferably coated on both sides with an adsorptive catalyst material, preferably platinum or a platinum alloy with ruthenium, tin and nickel. USE - Producing electrical energy by the direct conversion of chemical energy from oxidation processes. ADVANTAGE - The cell has a simple structure and has a high power density
