← ScienceWhich reaction outcome follows rapid fuel cell temperature elevation?
A)Increased kinetic energy lowers activation barrier
B)Catalyst poisoning decreases reaction efficiency
C)Increased entropy favors reactant reformation
D)Electrolyte evaporation decreases ion conductivity✓
💡 Explanation
Elevated temperatures accelerate electrolyte evaporation, reducing ion movement through the membrane, leading to decreased conductivity; because of this, the voltage drops, rather than catalysts failing, therefore this scenario limits current flow rather than affecting the activation energy.
