Abstract
A method of forming diffusion barrier layer includes providing an interconnect for a fuel cell stack, forming a glass barrier precursor layer over a Mn and/or Co containing electrically conductive contact layer on the interconnect, and heating the barrier precursor layer to precipitate crystals in the barrier precursor layer to convert the barrier precursor layer to a glass ceramic barrier layer.
