Abstract
HEXIS is developing and manufacturing SOFC-based micro-CHP systems for single-family or small multi-family houses. Galileo 1000 N with an output of 1 kW electrical power was brought into the market 2013. Since then, HEXIS together with other members of the Viessmann Group have been developing the next generation of the Viessmann/HEXIS SOFC system. The paper and presentation will report on the newest results of the short-stack tests, full-scale-stack tests as well as on system tests based on the established Galileo systems as well as on our next generation systems. These include results of Galileo tests running close to 25’000 h, electrical efficiencies of the new generation of 40 % AC, net and total efficiencies of 95 % (LHV).
