← ScienceWhich outcome results when a hydrogen fuel cell's membrane degrades?
A)Electrolyte leakage and reduced efficiency✓
B)Excessive water production at anode
C)Increased hydrogen concentration at cathode
D)Reduced catalyst surface area at anode
💡 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.
