COMMENTS In this fuel cell, the CO2 pressure on the anode and cathode enter the Nernst eqnation. The effect of a concentration difference is only a few millivolts, though, and the MCFC cannot withstand high pressure differentials between the anode and cathode due to the liquid electrolyte and material strength limits of the electrolyte matrix.
