Abstract
A solid oxide fuel cell generator () contains stacks of hollow axially elongated fuel cells () having an open top end (), an oxidant inlet plenum (), a feed fuel plenum (), a combustion chamber () for combusting reacted oxidant/spent fuel; and, optionally, a fuel recirculation chamber () below the combustion chamber (), where the fuel recirculation chamber () is in part defined by semi-porous fuel cell positioning gasket (), all within an outer generator enclosure (), wherein the fuel cell gasket () has a laminate structure comprising at least a compliant fibrous mat support layer and a strong, yet flexible woven layer, which may contain catalytic particles facing the combustion chamber, where the catalyst, if used, is effective to further oxidize exhaust fuel and protect the open top end () of the fuel cells.
