The anode substrate cell based SOFC stack technology from the Forschungszentrum Jülich has reached a maturity that allows for first trials of operation in external laboratories. The trials were conducted with kW-class stacks at VTT in Espoo Finland and at KIER in Daejeon South Korea. In preparation of the actual experiments personal from both institutes received training on stack operation and handling in the laboratories of the Forschungszentrum. Information and pre-requisites on the operational details and test stands were made available to the partners well in advance of the actual experiments. During the years 2004 and 2005 several tests were performed. At VTT a 1 kW-class and a 5 kW-class stack were installed and operated. At KIER two 0.5 kW-class stacks and two 5 kW-class stacks were installed and operated. Considering the difficulties of assembling and operating stacks in an unfamiliar environment the test results were quite satisfactory. All stacks reached their projected power or more. The lifetime of some of the stacks was however relatively short due to short circuits, leakage or problems with the test stands. One of the 5 kW-class stacks installed at VTT is successfully being operated in a system under varying conditions and fuel compositions. One of the 5 kW-class stacks at KIER was successfully operated at elevated pressure (3.5 bar) which resulted in a 20% power increase compared to measurements at the same current density under ambient pressure.
