SOFC and micro gas turbine (MGT) hybrid power generation system in Fig.1 (a) is expected as a solution for energy saving and less CO2 emission. High temperature pressure swing absorption (HT-PSA) in Fig.1 (b) is also expected as an efficient method for pure O2 production.

Applying HT-PSA to the pressurized high-temperature cathode off-gas of SOFC-MGT hybrid system, we are able to obtain pure O2 more efficiently than the other conventional method.

Using obtained O2 for anode off-gas oxidation, we can easily capture CO2, which leads to effective carbon-less or negative-carbon solution. Produced O2 are also useful for efficient gasification, which leads to CO2-capture IGFC system.

In this study, we performed basic performance tests of SOFC-MGT and HT-PSA systems. Using these results, we also studied expecting performance and technical issues of proposed SOFC application systems.
