Cathode for molten carbonate fuel cell
Patent
·
OSTI ID:7174544
This patent describes a porous sintered cathode useful for a molten carbonate fuel cell comprising a sintered mixture and electrolyte. The sintered mixture being of a first particulate material slightly soluble in the electrolyte present in the molten carbonate fuel and a second particulate material insoluble in the electrolyte, present in the molten carbonate fuel cell. The first material forming a skeletal structure coated by particles of the second material, the first and second particulate materials initially having average diameters not greater than about 10 microns. The sintered mixture having a porosity in the range of from about 60% to about 70% by volume at steady-state cell operating conditions and including macro-pores in the range of from about 25 to about 50 microns and micropores of about 0.1 microns.
