Hexis’ SOFC System Galileo 1000 N – Lab and Field Test Experiences

Galileo 1000 N is an SOFC-based micro-CHP system for single family homes. This contribution reports on the newest achievements in the lab on efficiency, durability and cyclability of SOFC stacks and complete micro-CHP systems. It also shows results of the field tests. Achievements are total efficiencies of 95% (LHV) and electrical efficiencies of around 35% (AC net, LHV). The longest system test had been running for more than 40 000 h. More recent tests have achieved power degradations below 1% per 1000 h and cycling tests have shown a tolerance against at least 20 on-off cycles. The contribution also reports on the next steps to market introduction of the Galileo 1000 N.
