Abstract
A gasket for sealing two mating surfaces of a fuel cell is described. The gasket has a core layer comprising exfoliated vermiculite. The core layer is interposed between a first and second coating layer, the said coating layers each comprising glass, glass-ceramic and/or ceramic material. Methods for producing gaskets according to the invention are also described. A solid oxide cell or a solid oxide cell component comprising one or more of the gaskets; use of the gasket to improve sealing properties in a solid oxide cell; and a method of producing a solid oxide cell or of sealing a solid oxide cell comprising incorporating at least one of the gaskets into the solid oxide cell are also defined.
