Abstract
Provided is a zinc air fuel cell with enhanced cell performance which includes a separator-electrode assembly including a perforated metal plate as a cathode current collector, a catalyst-coated carbon paper, a separator, a perforated metal plate as an anode current collector, and a tilted nonconductive support. A metal plate may be placed on the tilted nonconductive support and connected to the anode current collector in the separator-electrode assembly to enlarge the active area of the anode current collector. Performance may be efficiently enhanced by minimizing a distance between the anode current collector and the cathode current collector, and by adding a metal plate which plays a role of an additional anode current collector on the tilted nonconductive support so as to increase the overall active area of anode current collector contacting with zinc pellets and to resultantly enhance the ionization of zinc.
