1.	What is the overall efficiency of a fuel cell? (E=Delivered voltage, I=current delivered for a period of time T)(a) \(\frac{(EIT)}{∆H} \)(b) \(\frac{(ET)}{∆HI} \)(c) \(1-(\frac{(EIT)}{∆H}) \)(d) \(\frac{∆H}{EIT} \)I had been asked this question in an interview for internship.The question is from Inorganic Chemical in chapter Inorganic Chemical Industries of Chemical Technology
Answer» Correct option is (a) \(\frac{(EIT)}{∆H} \) Explanation: The overall efficiency of a FUEL cell is given by \(ƞ_o=\frac{EIT}{∆H}.\) It is the fraction of HEAT reaction of PRIMARY fuel converted into useful electric work at the device terminals.
