Thermodynamic analysis of a methane fed SOFC(H+) system is performed. It is stated that the fuel utilization depends on H2O/CH4 mole ratio in the feeding fuel mixture and has a maximum at the ratio of about 2.6. It is stated that average EMF of the SOFC(H+) is higher than that of an SOFC based on oxygen ion conductor under the same conditions and, hence, the maximum efficiency of the SOFC(H+) system is about 15 % higher than of the SOFC system based on oxygen ion conductor |
