Abstract: Disclosed herein is a separator for a molten carbonate fuel cell, the separator including four steel sheets in which edges of the four steel sheets are joined to each other thereby providing three spaces therebetween, comprising a cathode channel, serving as a flow path of oxidant gas, formed in the first space; an anode channel, serving as a flow path of fuel gas, formed in the second space such that the anode channel is separated from the cathode channel; and a fuel gas reforming channel formed in the third space, which is located between the first space and the second space. The separator for a molten carbonate fuel cell is advantageous in that the volume of the fuel cell is decreased, and the structure thereof is simple, thus reducing the production cost thereof.

Abstract: Disclosed is a separator plate for a molten carbonate fuel cell, which functions to reform a fuel gas while allowing it to efficiently flow therein and thereout, thus producing hydrogen and carbon dioxide, which are then supplied into an anode, and which functions to realize the electrical connection between the anode and the cathode. In the center plate, having a central portion and peripheral portions of the separator plate, the central portion has gas flow paths, that is, guide protrusions and guide grooves, and the peripheral portions are formed into sidewall parts through a folding process, and thus the number of constituents of the separator plate is minimized, thereby reducing the area to be welded. Further, the sidewall parts are integrally structured with the center plate, thereby increasing airtightness and solving problems of corrosion which may be caused in the welded area.

Abstract: The invention relates to a separator plate having a fuel reforming chamber for a molten carbonate fuel cell, which can be simply and easily manufactured to integrate the fuel reforming chamber, which enables indirect reforming, with a separator plate so as to realize uniform heat distribution of the separator plate, and to perform a fuel gas reforming reaction, which is an endothermic reaction, using heat generated during the operation of the fuel cell. According to the invention, a fuel gas such as methane (CH4) is supplied to a fuel reforming chamber to reform it therein so as to convert it into hydrogen, after which the converted fuel gas is supplied between the fuel gas guides of an anode part positioned directly on the fuel reforming chamber, and at the same time, an oxidizing gas is supplied between the oxidizing gas guides positioned directly beneath the fuel reforming chamber, thus generating electricity.
