Solid Oxide Fuel Cells are considered as one prime technology for residential CHP and power generation applications. Employment in these sectors requires long operational lifetime beyond 10 years. This corresponds to anything between 20,000 and 100,000 hours of operation. In order to ‘survive’ this extended period of time with the challenging conditions set by SOFC operating parameters (high temperatures, high water content, dual atmospheres across the interconnects etc.) the steel interconnects employed by most current developers require a protective coating to prevent excessive oxidation and release of chromium. A number of different coatings and coating processes have been suggested in the past, ranging from wet powder spraying of MnCo oxides to PVD coating of thin commercial steel sheets with Co and Ce.

The SCORED 2:0 is attempting to benchmark coating materials and the processes they are applied with. The project follows three goals:
1. analyse which is the best process to apply specific materials that have been discussed for SOFC interconnect protective coatings,
2. search for new materials and processes to apply protective coatings, and
3. benchmark the processes and materials against the commercial state of the art.

The expected outcome is a systematic analysis of the interplay between materials, steel substrate, and the physico-chemical processes used to apply the layers.
This contribution offers the overview and summary to the more specialised papers submitted in parallel.
