Which outcome occurs when an alkaline fuel cell membrane degrades?

💡 Explanation

Increased membrane crossover of hydroxide ions results because membrane degradation increases membrane porosity promoting **diffusion**. This causes increased ion transport across the membrane therefore decreasing efficiency rather than improved catalytic activity under other operating conditions.
