Abstract
A solid oxide fuel cell that is resistant to seal delamination is disclosed. The solid oxide fuel cell comprises, either individually or in combination, a solid electrically non -conductive frame, a seal structure comprising a material capable of preventing a transfer of charge across the seal during fuel cell operation, and a seal comprising a glass frit that is substantially free of oxides of lithium, sodium, or both lithium and sodium. Methods for manufacturing a solid oxide fuel cell are also disclosed.
