Abstract
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.
Claims7
A method for manufacturing a cathode for a molten carbonate fuel cell (MCFC), that is, an electrolyte impregnated cathode for the MCFC, the method comprising:
- uniformly applying eutectic carbonate electrolyte powder on a surface of the cathode;
- and
- performing heat-treatment to impregnate an electrolyte into pores of the cathode,
- wherein in the step of performing the heat-treatment, the applied eutectic carbonate electrolyte powder is pressed by a porous pressure plate having pores isolated from an outside of the pressure plate, and the pressure plate has a coated surface to prevent the cathode from adhering to the pressure plate,
- and in the step of performing the heat-treatment, the coated surface of the pressure plate covers the applied eutectic carbonate electrolyte powder.
