Barium calcium aluminum borosilicate glass (BCABS) is used as a sealant for Solid Oxide Fuel Cells (SOFCs) at 800 deg C. One major problem is the reaction of this glass with barium oxide and other materials in the composition such as Ba-Y-Co-Fe and Ba-Sr-Co-Fe used in the fuel cell components, leading to the formation and spreading of barium aluminosilicate glass on the surface of the fuel cells. The investigation found that adding 0.4 mol%ZrO2 to BCABS prevents the formation of barium aluminosilicate glass.
