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.
