A Ba-free sealing glass with a high CTE and excellent interface stability optimized for SOFC/SOEC stack applications
Abstract
A new glass-ceramic composition containing Si, Mg, Ca, Na, Al, Zr and Bis presented here as sealant for planar SOFCs/SOECs, with the aim ofjoining the metallic interconnect (Crofer22APU) to the solid oxide cell(YSZ electrolyte or CGO barrier layer). Characteristic temperature,thermo-mechanical properties and compositional variations are reviewedand discussed by thermal analyses and in situ XRD, in order to designand optimize the sealing profile and reduce the residual porosity. Theglass after heat treatment partially devitrifies into augite andnepheline with residual glass phase of around 64.3%; aftercrystallization the glass-ceramic sealant has a CTE of 12.8 x 10<sup>-6</sup> K <sup>−1</sup>and it is compliant with the other materials typically used for stackcomponents.. This work shows that the developed glass-ceramic cansuccessfully join the ceramic cell with the Crofer22APU (pre-oxidizedand alumina coating), proven by tests on small and large-scale samples.No signs of unwanted reactions at the glass-metal and the glass-cellinterface are observed and sufficient gas tightness is achieved.
