In the framework of the project FISR SOFC it has been realised the first SOFC stack prototype designed and realized in Italy. The aim is to operate the stack at intermediate temperatures between 600° and 800°C. The interconnectors are realised in ferritic stainless steel . This materials allow good thermal compatibility with the ceramic materials, high mechanical stability. The problems related with the cathodic corrosion have been mitigated by using perovkite coatings. The stack is equipped with 5 cells 10 x 10 cm2 (internal manifold) , connected in series and allocated on counterflow , parallel channels flow fields equipped with proper plenums for thermal management. Compresive gaskets have been adopted for the sealing. The cells are based on supporting NiO based electrodes with a bilayer electrolyte (ceria and zirconia) and a perovskite cathode. The stack is fed with hydrogen or humidified methane. The aim is to promote the use of sofc devices for distributed energy generation.
