Which outcome occurs when a catalyst degrades in fuel cell?

💡 Explanation

Because the catalyst is essential for lowering activation energy and increasing cell reaction rate, catalyst degradation diminishes its overall effectiveness via catalyst poisoning; therefore reaction rate slows down rather than the other effects which are not directly related.
