Consider a methaneoxygen fuel cell in which the reaction at the anode is CH 4 + 2H

Question:

Consider a methane–oxygen fuel cell in which the reaction at the anode is

CH₄ + 2H₂O → CO₂ + 8 e− + 8H+

The electrons produced by the reaction flow through the external load, and the positive ions migrate through the electrolyte to the cathode, where the reaction is

8 e− + 8H+ + 2O₂ → 4H₂O

Calculate the reversible work and the reversible EMF for the fuel cell operating at 25◦C, 100 kPa.
