Which risk increases during fuel cell operation at excessively low reactant flow rates?

💡 Explanation

Reduced reactant flow starves the anode, altering the electrode potential; because oxidation kinetics shift unfavorably, interfacial corrosion via the Nernst potential accelerates, rather than producing desirable products; therefore, corrosion increases rather than improves cell operation.
