In this study, we evaluated the performance of the air cathode prepared by our industrial partner in a customized test platform under operating conditions of temperature up to 70°C, potassium hydroxide (KOH) concentration approximately 45wt% and current density of 0.2A/cm2. The temperature and CO2 effect on the performance were also investigated. The air cathode performed for over 1000 hours lifetime with the best degradation rate of approximately 0.15mV/hr.
