The present invention relates to an electrolyte-impregnated, reinforced matrix for molten carbonate fuel cells and a manufacturing method thereof. According to the invention, the electrolyte-impregnated matrix, which comprises both the electrolyte and the reinforcing particles including a metal and an oxide, is manufactured by adding the electrolyte, as required per unit cell of a fuel cell, and the reinforcing particles including the metal and the oxide, to a slurry during the matrix preparation step, and subjecting the resulting slurry to a tape casting process. By doing so, the matrix stacking operation is facilitated, and the matrix manufacturing process is simplified. In addition, cracking caused by the difference in thermal expansion coefficient between an electrolyte sheet and the matrix can be suppressed, and thermal shock occurring during operation of the fuel cell stack can be reduced, thus improving the performance and lifetime of the fuel cell.

Reinforced matrix impregnated with electrolytes for molten carbonate fuel cell and fabrication method thereof

Disclosed is a method for manufacturing an electrode, that is, a large-sized cathode, used for a molten carbonate fuel cell. In the disclosed method, a substrate and a pressure plate, used for electrolyte impregnation, are surface-treated so as to control the bending and cracking of the electrode during the impregnation of an electrolyte.

Fabrication method of electrolyte impregnanted cathodes

Disclosed herein is a method of manufacturing an anode for in-situ sintering for a molten carbonate fuel cell, in which an anode green sheet is prepared using a slurry, and then a reinforcing layer is placed on the anode green sheet and then pressed, thereby improving the mechanical stability of a fuel cell stack and the long term stability of an anode, and an anode manufactured using the method.
