Patent ID: 8603702

Claim:
A zinc air fuel cell system comprising: a zinc air fuel cell comprising: an integrated separator-electrode assembly comprising: a perforated cathode, a catalyst-coated carbon paper, a separator, and a perforated anode; a tilted nonconductive support; a metal sheet on the tilted nonconductive support in which the metal sheet is electrically connected to the perforated anode; a tapered electrolyte chamber between the perforated anode and the metal sheet on the tilted nonconductive support; an electrolyte within the tapered electrolyte chamber and in fluid contacts with the metal sheet, the perforated anode, the separator, and the catalyst-coated carbon paper; zinc pellets in a portion of the electrolyte between the metal sheet on the tilted nonconductive support and the separator of the integrated separator-electrode assembly; a tank connected to the tapered electrolyte chamber, wherein the tank is configured to eliminate sedimentation that comprises zinc oxide powder and zinc particles from the electrolyte; a pump connected to the tank; and a zinc pellet reservoir connected to the flow into the tapered electrolyte chamber.
