Abstract

A dual compartment anode structure for use in molten carbonates fuel cells having an electrolyte porous metallic plate structure with one face adapted to contact the electrolyte and an opposite face having a plurality of ribs extending therefrom, a hydrogen ion and molecular hydrogen and electrolyte non-porous metallic foil having one face in contact with the ends of the ribs to define an anode reacton gas compartment therebetween, and a corrugated metallic current collector having a plurality of peaks with one face at the peaks in contact with the opposite face of the metallic foil defining an anode fuel gas compartment therbetween. The dual compartment anode structure of this invention provides separation between the electrolyte and the fuel thereby permitting internal cell reforming of hydrogen containing fuels without poisoning of the reforming catalyst and provides greater cell stability due to reduction in corrosion and reduced electrolyte and electrode loss.
