Abstract

The multi-section cathode air heat exchanger (102) includes at least a first heat exchanger section (104), and a fixed contact oxidation catalyzed section (126) secured adjacent each other in a stack association. Cool cathode inlet air flows through cool air channels (110) of the at least first (104) and oxidation catalyzed sections (126). Hot anode exhaust flows through hot air channels (124) of the oxidation catalyzed section (126) and is combusted therein. The combusted anode exhaust then flows through hot air channels (112) of the first section (104) of the cathode air heat exchanger (102). The cool and hot air channels (110, 112) are secured in direct heat exchange relationship with each other so that temperatures of the heat exchanger (102) do not exceed 800.degree. C. to minimize requirements for using expensive, high-temperature alloys.

Co-flow anode/cathode supply heat exchanger for a solid-oxide fuel cell assembly

Patent Haltiner, Jr., Karl J.; Kelly, Sean M.

In a solid-oxide fuel cell assembly, a co-flow heat exchanger is provided in the flow paths of the reformate gas and the cathode air ahead of the fuel cell stack, the reformate gas being on one side of the exchanger and the cathode air being on the other. The reformate gas is at a substantially higher temperature than is desired in the stack, and the cathode gas is substantially cooler than desired. In the co-flow heat exchanger, the temperatures of the reformate and cathode streams converge to nearly the same temperature at the outlet of the exchanger. Preferably, the heatmore » « less

Solid oxide fuel cell power plant having a bootstrap start-up system

Patent Lines, Michael T

The bootstrap start-up system (42) achieves an efficient start-up of the power plant (10) that minimizes formation of soot within a reformed hydrogen rich fuel. A burner (48) receives un-reformed fuel directly from the fuel supply (30) and combusts the fuel to heat cathode air which then heats an electrolyte (24) within the fuel cell (12). A dilute hydrogen forming gas (68) cycles through a sealed heat-cycling loop (66) to transfer heat and generated steam from an anode side (32) of the electrolyte (24) through fuel processing system (36) components (38, 40) and back to an anode flow field (26)more » « less

Solid oxide fuel cells having porous cathodes infiltrated with oxygen-reducing catalysts

Patent Liu, Meilin; Liu, Ze; Liu, Mingfei; ...

Solid-oxide fuel cells include an electrolyte and an anode electrically coupled to a first surface of the electrolyte. A cathode is provided, which is electrically coupled to a second surface of the electrolyte. The cathode includes a porous backbone having a porosity in a range from about 20% to about 70%. The porous backbone contains a mixed ionic-electronic conductor (MIEC) of a first material infiltrated with an oxygen-reducing catalyst of a second material different from the first material.

Solid-oxide fuel cell system having a fuel combustor to pre-heat reformer on start-up

Patent Schumann, David R.; Kelly, Sean M.; Haltiner, Jr., Karl J.

In a solid-oxide fuel cell system, a catalytic reformer unit provides reformate fuel for use by the cells in generating electricity. Both the reformer and the fuel cells require elevated temperatures for satisfactory operation. The reformer unit is provided with a combustion chamber and igniter ahead of the catalytic reformer plates such that, during start-up, fuel/air mixture normally destined for reformation may be ignited in the combustion chamber to provide a hot combustion exhaust which is fed through the catalytic reformer and the anode reformate flow spaces to assist in rapidly bringing the fuel cell system to operating temperature.
