The feasibility of adding glass to conventional SOFC cathode contact materials in order to improve bonding to adjacent materials in the cell stack is assessed. A variety of candidate glass compositions were added to LSM and SSC. The important properties of the resulting composites, including conductivity, sintering behavior, CTE, and adhesion to LSCF and MCO-coated 441 stainless steel were used as screening parameters. The most promising CCM/glass composites were coated onto MCO-coated 441 stainless steel substrates and subjected to ASR testing at 800° C. In all cases, ASR is found to be acceptable. Indeed, addition of glass is found to improve bonding of the CCM layer without sacrificing acceptable conductivity.
