You will have to compare the efficiencies of each of the fuel cells and also calculate the cell voltages achievable.
Based on these parameters and other factors such as operating temperature, harmful products etc
In order to calculate efficiencies and cell potentials one must first calculate enthalpies of reaction, entropies and then Gibbs free energy of the reaction. One can then compute the cell voltage. In order to then see the effect of concentration of reactants/products on this cell
voltage, the Nernst Equation should be used. Finally the efficiency can be worked out from a simple ratio: This should be done for a number of different fuel cell systems such as Oxygen/hyrdrogen and Direct Methanol Fuel Cell.
