Keywords: | Carbon/carbon composites;Electrocatalyst;Oxygen (air) electrodes;Zinc-air fuel cells | Issue Date: | 1-Jan-2002 | Journal: | Materials Science Forum | Abstract: | Porous C/C (carbonised resin/carbon fibre) composite, with a mass fraction of carbonised resin of 50% or 28%, surface doped with Pt, Ag, CoO, La2NiO4+La2CoO4 and La2NiO4+La2CoO4+Pt was used as a support of oxygen electrode in alkaline solution. The effects of various dopants on the oxygen reduction rate were compared on the basis of discharge behaviour of an air/zinc couple. A maximum power density amounting to 40 mV/cm2 was observed for the C/C composite with the resin fraction of 50%, catalyzed by an oxide mixture La2NiO4 + La2CoO4. |
