Which limit impacts the electrochemical reaction rate of a fuel cell?

💡 Explanation

Ion transport polarization affects the reaction rate, because limited ion mobility in the electrolyte slows reactions because the current cannot reach equilibrium instantly. Therefore, ion transport effects, rather than just catalyst area, fundamentally throttle the overall reaction rate.
