When calculating the total output of a hydrogen-oxygen fuel cell, should one work with the standard free energies of formation of the compounds involved (hydrogen, oxygen, and water) or just the standard enthalpies of formations? I believe free energy needs to be taken into account in order to properly estimate the total work output of the cell but I am not sure on this point.
