Development and Application of HVOF Sprayed Spinel Protective Coating for SOFC Interconnects

Comparison of iron and copper doped manganese cobalt spinel oxides as protective coatings for solid oxide fuel cell interconnects

“…Most studies of the oxidation resistance and ASR of FSS coated with Fe and Cu doped (Mn,Co) 3 O 4 are limited to relatively short exposure times (< 500 h) and do not provided a detailed investigation of the interaction between the coating and the FSS [16,17,[27][28][29][30]. Furthermore, since the ASR has been measured using different set-ups and contact electrodes, it is difficult to compare the performance of the different coating materials and thus evaluate whether Fe or Cu doping offers any benefit.…”

Microstructural and electrical characterization of Mn-Co spinel protective coatings for solid oxide cell interconnects

“…(Mn,Co)3O4 spinel coatings of different thickness have been produced by many different deposition techniques: slurry deposition of ceramic powders [15,[18][19][20], electrodeposition followed by oxidation [21][22][23], physical vapor deposition (PVD), thermal oxidation [24,25] and thermal spray [26][27][28][29].…”

Low temperature processed MnCo2O4 and MnCo1.8Fe0.2O4 as effective protective coatings for solid oxide fuel cell interconnects at 750 °C

“…Among many possible coatings [14][15][16][17][18][19][20][21], manganese cobalt spinels were studied extensively as protective coatings for SOFC/SOEC interconnects [14,22]. These materials are compatible with contact layer materials in the fuel cells and have also proven to effectively block chromium outward diffusion and evaporation.…”
