Which outcome occurs when a platinum catalyst degrades in a fuel cell?

💡 Explanation

Reduced cell voltage emerges because the degradation decreases the catalyst's effective surface area via poisoning. This suppresses the electro-catalytic reaction kinetics; therefore reduced voltage occurs rather than thermal or physical effects.
