High-Temperature Viscous Sealing Glasses for Solid Oxide Fuel Cells


Performer: Mo-Sci Corporation

Project No: SC0002491


Project Description

In Phase I of this work, Mo-Sci Corporation (Mo-Sci) developed a prototype viscous glass solid oxide fuel cell (SOFC) seal. Mo-Sci has identified new glass compositions that have the appropriate viscosity and stability for this application. In Phase II, the compositions will be optimized and tested under more stringent conditions. Candidate glasses will be tested to ensure they do not adversely react with other SOFC components and that desired viscous properties are retained over long periods of time (SOFC target lifetime is 40,000 hours). Down-selected candidate glasses will be used to construct prototype seals that will undergo thermal cycle testing. A successful glass seal will make SOFCs more robust devices, expanding the number of applications that SOFCs can fulfill.
