Engineered glass seals for solid-oxide fuel cells

Patent Surdoval, Wayne ; Lara-Curzio, Edgar ; Stevenson, Jeffry ; Muth, Joseph Thomas ; Armstrong, Beth L. ; Shyam, Amit ; Trejo, Rosa M. ; Wang, Yanli ; Chou, Yeong Shyung ; Shultz, Travis Ray

A seal for a solid oxide fuel cell includes a glass matrix having glass percolation therethrough and having a glass transition temperature below 650.degree. C. A deformable second phase material is dispersed in the glass matrix. The second phase material can be a compliant material. The second phase material can be a crushable material. A solid oxide fuel cell, a precursor for forming a seal for a solid oxide fuel cell, and a method of making a seal for a solid oxide fuel cell are also disclosed.

Solid oxide fuel cell having a glass composite seal

Patent De Rose, Anthony J. ; Mukerjee, Subhasish ; Haltiner, Jr., Karl Jacob

A solid oxide fuel cell stack having a plurality of cassettes and a glass composite seal disposed between the sealing surfaces of adjacent cassettes, thereby joining the cassettes and providing a hermetic seal therebetween. The glass composite seal includes an alkaline earth aluminosilicate (AEAS) glass disposed about a viscous glass such that the AEAS glass retains the viscous glass in a predetermined position between the first and second sealing surfaces. The AEAS glass provides geometric stability to the glass composite seal to maintain the proper distance between the adjacent cassettes while the viscous glass provides for a compliant and self-healingmore »« less
