High hydrogen concentration at fuel cell anodes causes which outcome?

A)Increased proton flux across membrane
B)Decreased catalyst surface area
C)Elevated oxygen reduction reaction rate
D)Reduced electron accumulation at cathode

💡 Explanation

Increased hydrogen leads to higher proton concentration, therefore Fick's Law of Diffusion causes higher proton flux across electrolyte. Higher proton driving force occurs, rather than changes in kinetics, cathode effects.
