A solid oxide fuel cell generator ( ) contains stacks ( ) of hollow, tubular axially elongated fuel cells ( ) which can operate to generate electricity; a single oxidant inlet plenum ( ) including a bottom enclosing member, having hole therethrough which acts as an oxidant feed tube positioning board ( ); a fuel inlet plenum ( ); an oxidant/fuel exhaust chamber ( ); power leads ( ) electrically connected to the fuel cells transverse to the axis ( ′) of the fuel calls; and a plurality of oxidant feed tubes ( ); all surrounded by insulation ( ); where there are at least two fuel cell stacks arranged in a row next to each other, the oxidant feed tube positioning board at the bottom of the oxidant inlet plenum is a laminate of layers of porous alumino-silicate ceramic fibers bonded with a ceramic alumina binder and dense woven ceramic ( ) impregnated with ceramic adhesive ( ), and wherein the insulation constitutes, primarily, bulk ceramic fibers.

429 31, 429 34, 429 35

A solid oxide fuel cell generator ( ), containing tubular fuel cells ( ) with interior air electrodes ( ), where a supporting member ( ) containing a plurality of holes ( ) supports oxidant feed tubes ( ), which pass from an oxidant plenum ( ) into the center of the fuel cells, through the holes ( ) in the supporting member ( ), where a compliant gasket ( ) around the top of the oxidant feed tubes and on top ( ) of the supporting member ( ) helps support the oxidant feed tubes and center them within the fuel cells, and loosen the tolerance for centering the air feed tubes.

An electrochemical apparatus (10) is made having a generator section (22) containing electrochemical cells (16), a fresh gaseous feed fuel inlet (28), a gaseous feed oxidant inlet (30), and at least one hot gaseous spent fuel recirculation channel (46), where the spent fuel recirculation channel (46), a portion of which is in contact with the outside of a mixer chamber (52), passes from the generator chamber (22) to combine with the fresh feed fuel inlet (28) at the entrance to the mixer chamber, and a mixer nozzle (50) is located at the entrance to the mixer chamber, where the mixer chamber (52) connects with the reforming chamber (54), and where the mixer-diffuser chamber (52) and mixer nozzle (50) are exterior to and spaced apart from the combustion chamber (24), and the generator chamber (22), and the mixer nozzle (50) can operate below 400. degree.
