Effects of operating parameters on the performance of a zinc-air fuel cell

Abstract

Abstract As a promising energy storage device, the rechargeable Zinc-air fuel cells (ZAFCs) has attracted an increasing attention because of their high energy density, cost-effectiveness, non-toxic (in terms of the manufacturing materials of the cell as well as the products of the reactions), the rich abundance of zinc, compact system design, as well as its environmental benignity. Rechargeable Zinc-air fuel cells (ZAFCs) are investigated as a possible technology for fast responding large-scale electrical energy. a broad study was performed to examine the influence of different ranges of parameters such as electrolyte flow rate (0-250 mL/min), electrolyte concentration (10- 60% by weight KOH), electrolyte temperature (26-60°C), active or passive air supply (0-8 L/min), and the effects of each parameter on the cell performance was studied and analysed and the best parameters were chosen to maintain the most effective cell operation.
