Exploring of the Oxygen Reduction Reaction on the Gas Diffusion Electrode for Zinc Air Fuel Cell

In this study, a three-layer gas diffusion electrode was made according to the second layer was made of a mixture of carbon black and Teflon with the ratio of 70:30 on a 200μm silver mesh. The third layer that cased of diffusion layer was made of platinum nano-clusters on carbon and Teflon suspension (with the 70:30 ratio). Finally the heat treated electrode was evaluated for oxygen reduction reaction in a three electrode configuration. The performance of electrode was considered in homemade zinc air fuel cell. The results showed that the open circuit voltage of cell was 1.346 V and at the voltage of 0.73 volt; the current density was 166.5 ( 2 mA/ cm ).
