Description
For plasma sprayed thin-film SOFCs porous metallic substrates were investigated regarding the required properties. The main essential properties are a sufficient electrical conductivity, a high temperature corrosion resistance and an adapted thermal expansion coefficient with respect to the other SOFC components. Proceeding from these requirements metallic materials such as a porous Cr-ODS alloy (Cr-5Fe-1Y2O3), a stainless steel plate (Fe-18Cr-12Ni-2Mo) and a Ni felt were tested. Additionally, to investigate the metallic substrates and their interaction with the layers of the cells completely plasma sprayed SOFCs were fabricated and electrochemically characterized. (author)
