MCQ
The efficiency of a fuel cell is given by
- A$\Delta G/\Delta S$
- ✓$\Delta G/\Delta H$
- C$\Delta S/\Delta G$
- D$\Delta H/\Delta G$
✓
Answer
Correct option: B.
$\Delta G/\Delta H$
b
Efficiency of a fuel cell $(\phi)=\frac{\Delta G}{\Delta H} \times 100$
Efficiency of a fuel cell $(\phi)=\frac{\Delta G}{\Delta H} \times 100$
Fuel cells are expected to have an efficiency of $100 \%$
