Which mechanism limits maximum power output in a fuel cell operating at elevated temperatures?

💡 Explanation

At elevated temperatures, electrolyte membrane degradation accelerates because increased thermal energy weakens the polymer structure, leading to reduced ion conductivity and fuel crossover. Therefore, power output reduces due to membrane compromise, rather than increased electrode area or diffusion which would instead enhance power.
