Abstract
Oxygen reduction mechanism on Au meniscus electrode in molten Li-Na carbonate at 650°C has been studied by analyzing the electrode reaction resistance measured with current double pulse method. The meniscus electrode composed of Au gauze were adhered onto the molten carbonates electrolyte tyle and sprayed CO2-O2-N2 mixed reactant gases at the flow rate of 100cm3/min, Investigating the dependencies of the electrode reaction resistances on CO2, O2 partial pressure and the i-V relations for O2 reduction, it was assumed to be atomic O formed by dissociation of O2 molecules at the electrode interface as the electrochemical reduction species.
