초록 ▼

An electrochemical fuel cell generator configuration is made having a generator section which contains a plurality of axially elongated fuel cells, each cell containing a fuel electrode, air electrode, and solid oxide electrolyte between the electrodes, in which axially elongated dividers separate portions of the fuel cells from each other, and where at least one divider also reforms a reformable fuel gas mixture prior to electricity generation reactions, the at least one reformer-divider is hollow having a closed end and an open end entrance for a reformable fuel mixture to pass to the closed end of the divider and then reverse flow and pass back along the hollowed walls to be reformed, and then finally to pass as reformed fuel out of the open end of the divider to contact the fuel cells, and further where the reformer-divider is a composite structure having a gas diffusion barrier of metallic foil surrounding the external walls of the reformer-divider except at the entrance to prevent diffusion of the reformable gas mixture through the divider, and further housed in an outer insulating jacket except at the entrance to prevent short-circuiting of the fuel cells by the gas diffusion barrier.

대표청구항 ▼

[ We claim:] [1.] An electrochemical fuel cell generator configuration, which comprises: a plurality of electrically connected, axially elongated, electrochemical fuel cells, each fuel cell having an outer electrode, an inner electrode, and a solid oxide electrolyte positioned between the electrodes, in which axially elongated dividers are positioned between and separate the fuel cells, and further in which a least one of the axially elongated dividers is hollow in a portion along the length having an open end and a closed end within solid elongated walls, the hollow portion containing a catalytic reforming material, a reformable fuel mixture inlet channel, a reformed fuel exit channel to the fuel cells, and the hollow divider further containing a means effective to prevent reformable fuel mixture gas leakage from the divider to the fuel cells, in which the means to prevent gas leakage comprises the solid elongated walls of the hollow divider being surrounded by a metallic foil layer, except at the reformable fuel mixture inlet, forming a hollow divider-metallic foil subassembly.
