Abstract
Electrochemical partial oxidation (EPOx) of methane can convert exhaust heat into electricity as much as difference between change of Gibbs free energy and change of enthalpy. In this paper, we considered 30 kW power generation system combined Micro Gas Turbine and the Partial Oxdation Solid Oxide Fuel Cell using Gadolinium Doped Ceria as the electrolyte that has high oxide ion conductivity below 600°C. The cylindrical-shaped POSOFC is operated at 572°C recovering turbine exhaust heat of 593°C and accompanying production of hydrogen and carbon monoxide. According to the result of process simulation coupling with SOFC simulation including detailed polarization models, only addition of 16 liter POSOFC can increases the power generation efficiency by 8.5 points at fuel utilization of 80.1%.
