AMlience, O1T 44601 Recently, chess has boon a great deal of interest in research, development, and couunersialization of solid oxice fuel cctls. Joining and scaling arc critical issnes chet will need to be suldresseh before SOFCa can truly perform as expected, Ceramics aul melals oan le diffieull w joie together, especially wien the jaint yaust wilhstund up lo 900°C eperating temperature af The SOWCs. The goal of The present sindy is te Find rhe most suitable brave material for joining of lois stabilizee zirconia (YSZ) to stainless steels. A number of commercially available beare materials TiCusil, TICaNi, Conper-ADA, Gold-ABA, and CellLABA-Y have been evaluate. The oxidation behavior of the braze mater-als and steel substrates ia air was also examined through chormogravimmctric analysis. Lhe microst-ucture and compesition of the beszed regions have Been examined by optical and scanning clooron micioscopy aud EDS analysis, Hffeot of hove coeposition and srocessing conditions on the interfscial microstructure and composition of the jin eegions will he presente.
