← ScienceWhich outcome increases when fuel cell membrane dries?
A)Internal resistance becomes exponentially larger✓
B)Electrolyte conductivity rises dramatically
C)Open-circuit potential increases steadily
D)Faradaic efficiency reaches theoretical limits
💡 Explanation
Increased membrane resistance causes ohmic losses because ionic transport requires hydrated polymers; therefore fuel cell current drops considerably rather than improving while hydrated conditions would maintain efficiency.
