摘要
Sealant compositions particularly suitable for solid oxide fuel cell sealant are provided and preferably comprise glass matrix and ceramic fiber, wherein glass matrix and ceramic fiber are mixed in an volume ratio of 25:75-75:25 in the sealant, and the ceramic fibers are preferably uniformly dispersed in the sealant to exhibit an orientation. Methods to manufacture the sealant compositions also are provided. Particularly preferred sealant compositions of the invention can efficiently avoid undesired viscous flow of glass matrix, precisely locate the stack of fuel cell on the region to be sealed, and maintain uniform sealing ability under various changes in size of the fuel cell stack.
