Abstract

The experimental study on the improvement of zinc - air fuel cell performance was carried out for flowing electrolyte with and without gelling agent. The discharge capacity was measured with Chronoamperometry method at constant 0.7 volt. The average current with flowing electrolyte provided 27% higher than that with non-flowing electrolyte. he gelled KOH did not significantly affect the cell performance and provided lower amount of gas evolution. The surface morphology of zinc powder before and after cell testing was characterized by using scanning electron microscope (SEM). ฉ 2013 The Authors. Published by Elsevier B.V.
