“…These schemes can be divided into four groups: direct thermal coupling, indirect thermal coupling, fuel coupling and the advanced integration cycles for improved power generation (Zhang, et al, 2010). There are also possibilities to couple more than just the MGT and the SOFC into one machine.…”

The improvement of decentralised energy supply systems has received an important role in the recent years. One option is the combination of SOFC with recuperated MGT. Here, a new strategy for selecting the system parameters, such as the operating temperature of the SOFC, turbine inlet temperature and the pressure ratio of the hybrid system, is presented. By introducing the heat ratio between the heat required to increase the process gas to the SOFC operating temperature and the heat required to raise the SOCF exhaust gas to the TIT, it was found that high efficiency (approx. 68%) is realisable in a compact hybrid system today. Analysis also shows that the HEX-technology is needed to improve the system effectiveness. Also, high recirculation rates with lower TIT can be considered as the future development direction. In addition, a sample configuration of an oil-free MGT rotor unit with high speed foil bearings is presented.

“…The ones of the most promising types of fuel cells are solid oxide fuel cells (SOFC). They have high efficiency, they can be fueled by either hydrogen or hydrocarbons and do not include any moving parts, which might reduce durability [1]. SOFCs usually consist of ceramic or cermet, porous electrodes separated by a dense, oxide-ion conducting ceramic membrane, usually made of yttria-stabilized zirconia (YSZ).…”

Porous and about 40-μm-thick LNF cathodes were deposited on both sides of the substrate and sintered at 1100°C. Different thicknesses of the thin perovskite layer were investigated in order to find the most effective one and to better understand its influence on the cathode/electrolyte interface. It was found that approximately 150 nm LNF or LSCF layer is sufficient to minimize interface resistance and improve cathode reproducibility. It was concluded that the thin perovskite layer increases contact area and improves the oxygen ion transport between the cathode and electrolyte without influencing the oxygen reduction reaction mechanism.
