Study of CO poisoning of platinum and other alloy electrodes are usually carried out in aqueous electrolyte on a pre-adsorbed monolayer of CO . The effect of CO poisoning on the performance of Fuel Cells have been studies previously . However, both these techniques have their own limitations in estimating the rates of CO adsorption, desorption, and oxidation on composite electrodes. In this study, we conduct experiments on a fully assembled fuel to estimate the rates of CO adsorption, desorption and oxidation under different temperature conditions.
