Summary

Co-fired planar solid oxide fuel cells (SOFCs) were fabricated using tape-casting and screen printing technique. the mechanical strength of bare electrolyte and co-fired electrolyte supported cells (ESC) were measured. Testing results indicate that the co-fired cell strength is significantly lower than that of bare electrolyte. One of the major reasons for co-fired cell weakness is the thermal expansion coefficient mismatch between the anode and electrolyte, leading to the formation of microcracks within the anode. These microcracks can propagate through the anode-electrolyte interface and into the electrolyte substrate. Co-fired ESC performance and mechanical strength have been significantly improved through development of an alternative electrolyte material and improved electrodes.
