High temperature solid oxide fuel cells (SOFC) are simple electrochemical devices that operate at 1000°C and are capable of converting the chemical energy of natural gas fuel into AC electric power at approximately 50+60% electric efficiency (net AC/LHV at atmospheric pressure). Because of their high temperature of operation, pressurized SOFC may be used instead of a combustion chamber in gas turbines (GT). It leads to a new device such as SOFC/GT hybrid cycle. These power plants are expected to reach electric efficiency over 70%, bigger than conventional ones consisting of gas and steam turbines, and offer a clean, pollution free technology, to produce electricity. This article reviews and develops SOFC's performance and hybrid cycle SOFC/GT with pressurized fuel cell. The modelling of SOFC and a gas turbine is performed by means of own subroutines implemented into in-house code called COM-GAS. The model prepared by the authors, has been verified through the use of Hagi-wara's experimental data for SOFC.
