Which failure decreases fuel cell efficiency when using high hydrogen pressure?

💡 Explanation

Gas permeation through thinner polymeric membranes increases at high pressure, therefore hydrogen molecules diffuse across; this lowers the fuel cell efficiency, rather than performance increasing due to proper hydrogen reactions.
