Which consequence accelerates fuel cell degradation when temperature drops?

💡 Explanation

Increased catalyst poisoning is seen because reduced operating temperature slows reaction rates, therefore contaminants like CO bind more strongly to the platinum catalyst through stronger adsorption, rather than being oxidized; at higher temperatures, oxidation clears the surface.
