1.The efficiency of a fuel cell is given by:a.η=nFEcellΔH×100\eta = \frac{nFE_{cell}}{\Delta H} \times 100η=ΔHnFEcell×100b.η=nFEcellΔS×100\eta = \frac{nFE_{cell}}{\Delta S} \times 100η=ΔSnFEcell×100c.η=nFEcellΔA×100\eta = \frac{nFE_{cell}}{\Delta A} \times 100η=ΔAnFEcell×100d.None of the aboveLogin to continueOnly logged in users canattempt or see the solution.
