Thus far, tubular design cells are the most reliable cells against thermal stresses and chemical degradation of the performance. Siemens Power Generation has demonstrated the performance and reliability of SOFC systems with tubular cells [6], The 100 kW CHP system has been operated for more than 20000 h, and it was reported that no degradation of the system was observed. To prove the feasibility of a GT/SOFC hybrid system, a 220-kW hybrid system with an SOFC generator integrated with a micro gas turbine has been demonstrated at the University of California this system has shown a conversion efficiency of around 49% (HHV). 

Mehra and Ayon [76] developed the first micro structured hydrogen combustor made of silicon. The device was developed to power a micro gas turbine. However, it could also be applied for fuel processing and is therefore included in this chapter.

Especially with the key applications of jet engines and gas turbines for power generation, the field of gas turhine technology is likely to keep its great relevancy. The quest for more efficient gas turbines that comhust their fuel with as little emissions as possible will continue to motivate major developments in the field. If gas turbines can become an ever-more efficient and low-emission source of generating power they have the potential, like fuel cells, to become part of the next generation of power sources. There is also much promise linked to micro gas turbines as a source of efficient, affordable, clean, and decentralized power.

The case of pure electricity generation witfi an SOFC unit is represented by the data points with equal tjei and 1) 1. for instance, 0.7, 0.7. At this specific point, the CO2 reduction is about 35% and not more, due to the considerable loss of 30% of the energy input. A higher electrical efficiency hardly appears feasible, though a combination of an SOFC with a (micro) gas turbine could lead to tjei of up to 75% [15]. Total energy efficiency, nevertheless, is doubled.
