The　interfacial　reaction　between　sealing　glasses　and　Cr-containing　interconnect　presents　a　challenge　for　the　development　of　solid　oxide　fuel　cell　(SOFC).　In　this　work,　we　report　that　the　interfacial　reaction　between　bismuth-containing　sealing　glasses　and　Cr-containing　interconnect　can　be　tailored　by　ZnO　dopant.　The　addition　of　ZnO　contributes　to　a　more　open　glass　structure,　resulting　in　the　facilitated　diffusion　of　ions　in　glass　and　thus　the　increase　in　the　interfacial　reaction.　On　the　other　hand,　the　further　increase　in　ZnO　content　enhances　the　Bi3+→Bi5+　transition　in　glasses　and　reduces　the　redox　interfacial　reaction　by　consuming　the　oxygen　available　at　the　glass/metal　interface.　In　addition,　good　joining　can　be　observed　at　the　sealing　interface　between　ZnO-containing　glass-ceramics　and　Crofer　22　APU,　held　in　air　at　700°C　for　1400　h.　Moreover,　the　glass-ceramics　show　considerable　electrical　stability　in　oxidizing　and　reducing　atmospheres.　The　reported　results　support　the　suitability　of　prepared　glass-ceramics　as　sealing　materials　for　SOFC　applications.　©　2015　The　American　Ceramic　Society.
