Within the scope of a hybrid power plant project a micro gas turbine test rig was developed and is actually under construction at the DLR Institute of Combustion Technology. The test rig consists of a Turbec T100PH micro gas turbine and the required piping system for the hybrid application. Instead of a real solid oxide fuel cell (SOFC) stack a fuel cell simulator is used to avoid any risks for the sensitive and expensive real device. This simulator is able to emulate the SOFC interface conditions. The present paper reports the underlying pressurized hybrid power plant cycle, the setup of the test rig and the selection of the subsystems. Initially the micro gas turbine, equipped with a detailed instrumentation, was analyzed separately. First experimental data obtained with the micro gas turbine are presented.
