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 ( &prime;) 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.

Low-cost atmospheric SOFC power generation system

A solid oxide fuel cell (,) having a closed end (,) and an open end (,) operates in a fuel cell generator (,) where the fuel cell open end (,) of each fuel cell contains a sleeve (,) fitted over the open end (,), where the sleeve (,) extends beyond the open end (,) of the fuel cell (,) to prevent degradation of the interior air electrode of the fuel cell by fuel gas during operation of the generator (,).
