Which outcome raises fuel cell voltage when fuel starvation arises?

A)Reversal of electrochemical reaction
B)Increased ionic membrane conductivity
C)Enhanced platinum catalyst oxidation
D)Elevated operating temperature threshold

💡 Explanation

Fuel starvation permits the reversal of the electrochemical reaction at the anode because depletion forces the platinum catalyst to oxidize, generating oxygen rather than consuming fuel. Therefore, cell voltage rises, rather than remaining stable because the Nernst potential changes.
