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.

A fuel cell system includes a fuel cell stack, which during operation generates electrical energy by reacting a first stream of reactant gas and a second stream of reactant gas. The fuel cell stack also produces a fuel cell exhaust stream. An oxidizer unit is positioned to receive the fuel cell exhaust stream and oxidize at least a part of the fuel cell exhaust stream during operation, to produce an oxidizer exhaust stream. A heat recovery system is positioned to receive the oxidizer exhaust stream. The heat recovery system transfers at least some heat from the oxidizer exhaust stream to an input stream to generate a heated stream of water. In some embodiments, a temperature sensor is positioned to sense the temperature of the heated input stream. A control system maintains the heated stream of water at a target temperature based on the sensed temperature by controlling the amount of the heat from the oxidizer exhaust stream that is transferred to the input stream.
