← ScienceWithin a fuel cell, which outcome results when proton transport is hindered?
A)Lower cell voltage and efficiency✓
B)Increased water generation at anode
C)Elevated platinum catalyst dissolution
D)Decreased cell internal impedance
💡 Explanation
Reduced proton flow increases resistance impacting the electrochemical reaction, because slower *Helmholtz layer* formation limits the Hydrogen Oxidation Reaction. Therefore, the cell voltage decreases, because total available energy drops rather than other failures when protons are freely available.
