Which consequence results when a biochemical fuel cell's catalyst deactivates?

💡 Explanation

Deactivation increases the activation energy requirement because the catalyst no longer provides an alternative reaction pathway with a lower energy barrier; therefore more energy is needed for reactions, rather than a lower equilibrium barrier alone, under the original conditions.
