    摘要： Provided is a zinc air fuel cell with enhanced cell performance, more particularly a zinc air fuel cell 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. Furthermore, 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. For the zinc air fuel cell according to the present invention, a manufacturing cost may be reduced by using a mixture of MnO2 and CeO2, which are low-priced metal oxides as catalyst materials for oxygen reduction, and by using a low-priced nylon filter, which has a micro-porous structure and shows high stability in alkaline electrolyte. According to the present invention, the performance of the zinc air fuel cell may be efficiently enhanced by using a separator-electrode assembly structure, which minimize 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.
