Abstract: A fuel cell assembly comprising a plurality of individual fuel cells, especially a solid-oxide fuel cell assembly. The cells are organized into a plurality of stacks, preferably two stacks, disposed side-by-side rather than end-to-end as in a prior art monolithic single stack. This arrangement makes the assembly compact physically, which can be highly desirable in some fuel cell applications. The stacks are connected conventionally in series electrically but are supplied with air and fuel in parallel to shorten the distribution manifolds and improve uniformity of distribution and exhaust among all the cells.

Abstract: A solid-oxide fuel cell assembly comprising a stack of individual fuel cells for use as an auxiliary power unit in a vehicle. Each cell generates between 0.7V and 1.0 volts, depending upon load. The total output voltage of the assembly must be maintained between 42V and 48V. An assembly comprising 60 cells is optimal for automotive use, being the minimum number of cells required to provide a minimum of 42V (0.7 times 60) under high load, and requiring the minimum voltage control at low loads 1.0V times 60) to provide a maximum of 48V.

Abstract: A system for adding sulfur to a fuel cell stack, having a reformer adapted to reform a hydrocarbon fuel stream containing sulfur contaminants, thereby providing a reformate stream having sulfur; a sulfur trap fluidly coupled downstream of the reformer for removing sulfur from the reformate stream, thereby providing a desulfurized reformate stream; and a metering device in fluid communication with the reformate stream upstream of the sulfur trap and with the desulfurized reformate stream downstream of the sulfur trap. The metering device is adapted to bypass a portion of the reformate stream to mix with the desulfurized reformate stream, thereby producing a conditioned reformate stream having a predetermined sulfur concentration that gives an acceptable balance of minimal drop in initial power with the desired maximum stability of operation over prolonged periods for the fuel cell stack.

Abstract: A fuel cell module having four sheet metal parts stamped from flat stock. The parts do not require any forming operations such as folding or dishing. Each part may have a different thickness to suit its function. The first part is a cell mounting frame for receiving and supporting a PEN fuel cell element. The second part is a cathode spacer, the thickness of the spacer determining the height of the cathode air flow field. The third part is an anode spacer, the thickness of spacer determining the height of the anode fuel flow field. The fourth part is a separator plate for separating the anode gas flow in one cell from the cathode air flow in an adjacent cell in a fuel cell stack. The four plates are joined by welding or brazing and may be assembled in any order or combination which suits the assembly process. Any desired number of modules may be stacked together to form a fuel cell stack.

Abstract: Interconnects and perimeter spacers for a fuel cell stack are provided as flexible elements which can conform to non-planarities in a stack's electrolyte elements and thereby avoid inducing torsional stresses in the electrolyte elements. The interconnects are foil elements about 0.005inches thick, formed of a superalloy such as Hastelloy, Haynes 230, or a stainless steel. The perimeter spacers comprise a plurality of laminate thin spacer elements, each thin spacer element being a laminate of superalloy and a "soft" material such as copper, nickel, or mica. The spacer elements can slide past one another; thus the perimeter spacers can be physically thick, to form the gas flow spaces within the stack, while also being torsionally flexible.
