Which outcome results when a hydrogen fuel cell's membrane degrades?

💡 Explanation

Electrolyte leakage reduces efficiency as membrane degradation allows crossover. This **pervaporation** lets reactants mix directly, therefore overall voltage decreases, rather than hydrogen buildup, and it occurs due to membrane breakdown, not altered electrode properties.
