The feasibility of adding inorganic binder to conventional SOFC cathode contact materials in order to improve bonding to adjacent materials in the cell stack is assessed. A variety of candidate binder compositions are added to LSM. The important properties of the resulting composites, including ASR, reactivity, and adhesion to LSCF and MCO-coated 441 stainless steel are used as screening parameters. The most promising CCM/binder composites are coated onto MCO-coated 441 coupons and anode-supported button cells with LSCF cathode, and tested at 800 °C. It is found that a LSM-644A composite displayed excellent initial performance and promising stability. Indeed, addition of binder is found to improve bonding of the CCM layer without sacrificing CCM conductivity.
