Abstract:
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 ( â²) 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.
