Dots are the DFT calculated values, lines are polynomial interpolations. a Calculated total energy vs. system charge \({N}_{e}^{{\rm{net}}}\) including a second-order polynomial fit. b Fit residues for a second- and fifth-order fit. c Charge-equilibrated excess energies \({{\mathcal{G}}}_{{\rm{exc}}}^{\alpha }({\Phi }_{E})/2A\) for clean and H(fcc)-covered Pt(111) at applied electrode potential ΦE for pH = 0, including second-order fits.
