Simulation Of Carbon Monoxide Poisoning On The Bi-layered Anode Catalyst Layer
Simulation on bi-layered composite anode catalyst layer (ACL) shows a preceding filtration barrier for the oxidation of poisoning species carbon monoxide favors the subsequent active layer for the reaction of hydrogen. Appropriate thickness combination of the two layers is important for the effectiveness of the composite ACL. Synergistic effect is observed only when the filtration layer attains a sufficient diffusion length and residence time for the oxidation of carbon monoxide. Finite length of active layer is also required for sufficient catalytic surface area; however, extra length of the second layer renders a waste of catalyst materials and increased ionic resistivity of the ACL.
