The efficiency of a fuel cell is given by
  1. A
    Δ\DeltaΔG/Δ\DeltaΔS
  2. B
    Δ\DeltaΔG/Δ\DeltaΔH
  3. C
    Δ\DeltaΔS/Δ\DeltaΔG
  4. D

View written solutionFree

Correct answer: B

Efficiency of a fuel cell (ϕ\phi ϕ) = ΔGΔH×100{{\Delta G} \over {\Delta H}} \times 100ΔHΔG​×100

Generally, fuel cells are expected to have an efficiency of 100 percent.
