- Abstract
- Protective coatings based on cobalt-manganese spinel for solid oxide fuel cells (SOFC) interconnects made of stainless steel were obtained by non-stationary electrolysis. The main phase of the obtained coatings according to X-ray diffraction data is CoMnO. The evolution of the microstructure of the obtained coatings in the operating mode of the SOFC cathode chamber was studied. It was found that during the oxidation process, chromium and iron, which are components of the substrate, diffuse into the coating, oxidize, and the coating itself, after current life tests, is a mixture of CoMnO, FeO and CrO oxides. The study of the dependence of the area-specific resistant of the contact layer interconnected to the time spent under current load in the model conditions of the SOFC cathode chamber for 1000 hours on measuring assemblies at 850°C, under a current load of 0.5 A·cm, showed that the resistance is about 35 mOm· cm.
