Consider a methane-oxygen fuel cell in which the reaction at the anode is CH4 + 2H2O CO2 + 8e– + 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 8e– + 8 H+ + 2O2 4 H2O
a. Calculate the reversible work and the reversible EMS for the fuel cell operating at 25C, 100 kPa.
b. Repeat part (a), but assume that the fuel cell operates at 600 K instead of at room temperature.
