Abstract
To provide effective seals between the separator plates of fuel cells, particularly planar solid oxide fuel cells (SOFC's), a method of applying a glass-ceramic coating to such a separator plate comprises providing a laminar body incorporating a glass powder, e.g., a tape-cast sheet, forming a bond between the laminar body and the separator plate to form. an assembly comprising the separator plate and the laminar body, and heat-treating the assembly to convert the glass powder to a glass-ceramic.
