Cathode composite for molten carbonate fuel cell
A cathode composite useful for a molten carbonate fuel cell comprised of a porous sintered cathode having a porous sintered bubble pressure barrier integrally sintered to one face thereof, said cathode composite having a porosity ranging from about 25% by volume to about 75% by volume of the total volume of said composite, said cathode having a porosity ranging from about 25% by volume to about 75% by volume of the total volume of said cathode, said pressure barrier having a porosity ranging from about 25% by volume to about 75% by volume of the total volume of said barrier, said cathode having a median pore size ranging from in excess of one micron to about 10 microns, said barrier having a median pore size significantly smaller than that of said cathode, said cathode and said pressure barrier being comprised of from about 10 weight % to about 90 weight % Li /SUB x/ Ni(/sub 1//sub -/ /SUB x/)O/balance Li /SUB y/ Cu(/sub 1//sub -/ /SUB y/)O, where x and y each ranges from about 0.005 to about 0.25.
