Abstract:
This work deals with the design, the characterization, and testing of a novel glass‐ceramic to be used as sealant for planar solid oxide fuel cells and its compatibility with Mn 1.5 Co 1.5 O 4 ‐coated Crofer22 APU . Thermal, sintering, and crystallization behavior and thermo mechanical properties of the sealant are reviewed and discussed, indicating therefore that these compositions can be deposited at 850°C and provide an excellent compatibility with both the Mn 1.5 Co 1.5 O 4 ‐coated Crofer22 APU and the anode‐supported electrolyte. In particular, Mn 1.5 Co 1.5 O 4 ‐coated Crofer22 APU /sealant/anode‐supported‐electrolyte joined samples have been submitted to thermal tests (in air atmosphere) from RT to 800°C ( SOFC operating temperature) up to 500 h. No interactions, cracks formation, or failure were observed at the Mn 1.5 Co 1.5 O 4 ‐coated Crofer22 APU /sealant interface and between the glass‐ceramic and the anode‐supported‐electrolyte after 500 h of thermal tests in air atmosphere.
