Compressive Mica Seals for SOFC Applications
Journal Article
·
· Journal of Power Sources
Muscovite and phlogopite micas have been assessed as SOFC seals at 800C. Paper gaskets, composed of pressed mica platelets in an organic binder, proved ineffective seal materials predominantly because of their uneven surface. However, cleaved natural mica sheets (with no binder) indicated far superior sealing characteristics with leak rates lower than 0.1 sccm. cm-1 at 800C, and approximately 0.7 MPa (100 psi) compressive stress.
