Which consequence arises when exceeding the maximum allowed concentration of dissolved oxygen molecules within a polymer electrolyte membrane fuel cell?

💡 Explanation

Excessive dissolved oxygen drives accelerated platinum dissolution via oxidative corrosion because the Pt atoms readily form soluble oxides. Therefore the catalyst degrades faster, rather than increased resistance developing at the electrodes; that is tied to water management issues.
