Thermodynamic analysis of hydrogen production for fuel cells from oxidative steam reforming of methanol

► A thermodynamics analysis of the oxidative steam reforming of methanol. ► Water favors hydrogen production and the suppression of by-products. ► Oxygen addition lowers hydrogen yield significantly. ► Optimal conditions are 600 °C, H2O/MeOH ratio = 6.0-8.0 and O2/MeOH ratio = 0. ► The potential of methane formation at low temperatures is very high.
