Thermochemical calculations have been performed to derive equilibrium products and their compositions in the temperature range between 100° and 1000°C for various possible SOFC fuels including natural gas, liquefied petroleum gas, gasoline, kerosene, alcohols (methanol, ethanol, propanol), dimethyl ether, biogas, and coke oven gas. The minimum amounts of steam and oxygen to prevent carbon deposition are derived. The carbon-hydrogen-oxygen (C-H-O) ternary diagrams have been constructed, describing relevant operational conditions such as carbon deposition region, electromotive force, and gas partial pressures.
