Current issues for the commercialization of SOFC technology include high initial cost, poor performance stability, etc. In order to address these issues, new contact materials and processes need to be explored. Using Co and Mn starting powders, MnCo2O4 spinel contact layers were synthesized via screen printing and reactive sintering. The effect of heating rate on the sintering of Co and Mn to reactively form MnCo2O4 spinel was studied using in-situ HT-XRD, TGA-DSC, and microstructural analysis. The performance of the contact material was critically assessed with regard to its porosity, ASR, interaction with interconnect and cathode, and resistance to Cr migration. The beneficial effect of higher heating rates was analyzed and a mechanistic explanation was provided.
