The present invention relates to a membrane electrode unit for a fuel cell comprising an anode optionally coated with a catalyst, a cathode optionally coated with a catalyst, and a quantum conductor between the anode and the cathode. The quantum conductor is formed of a fine fiber fleece material impregnated to an saturation point with an electrolyte, the fleece material being chemically inert to the electrolyte under temperature and redox conditions up to + 200 ° C., and the weight of the fleece material is 20 to 200 g / m 2, the thickness of the fleece material is at most 1 mm and the pore volume is 65 to 92%. |
