DIRECT OXIDATION FUEL CELLS WITH IMPROVED CATHODE GAS DIFFUSION MEDIA FOR LOW AIR STOICHIOMETRY OPERATION |
摘要 |
A cathode for use in a direct oxidation fuel cell (DOFC) comprises a gas diffusion medium (GDM) including a backing layer and a microporous layer comprising a fluoropolymer and an electrically conductive material, wherein loading of the fluoropolymer in the microporous layer is in the range from about 10 to about 60 wt. %. In use, a concentrated solution of a liquid fuel is supplied to an anode and an oxidant to the cathode of the fuel cell, and the fuel cell may be operated at a low oxidant stoichiometry not greater than about 2.5.
