Overview on the Jülich SOFC Development Status

The SOFC group at JULICH works on the development of materials, cell and stack since the early 90s, strongly supported by post-operational analysis. Important achievements are e.g. the development of ferritic chromium steels which are now commercially available and anode substrate cells with power densities exceeding 2 W/cm² at 0.7 V and 700 °C. Special highlights are long term tests with short stacks of which one has reached 50,000 h of continuous operation. In the year 2000 also systems and system components development has been started. In 2012 a 20 kW system, based on four 5 kW stacks, was successfully set into operation. The envisaged 20 kW were achieved and the system has been operated for about 4,000 h up to now.
