Which of the following statement is true regarding efficiencies of fuel cell?(a) ƞ0 = ƞr(b) ƞ0 > ƞr(c) ƞ0 < ƞr(d) ƞ0 ≤ ƞrThis question was addressed to me in an internship interview.This intriguing question comes from Inorganic Chemical topic in portion Inorganic Chemical Industries of Chemical Technology

Answer»

Correct answer is (c) ƞ0 < ƞr

Best EXPLANATION: ƞ0 < ƞr. ƞ0 is the overall efficiency of the FUEL cell which includes incorrect ∆H at the electrodes, I^2 Rlosses from cell resistances and polarizability. Hence overall efficiency is always less than the reversible or IDEAL efficiency.
