Patent attributes
Disclosed is a molten carbonate fuel cell capable of preventing the leakage of a fuel gas due to deterioration of material by suppressing a high temperature generated at a hot section within a unit cell, thereby improving the reliability thereof. The present invention provides a molten carbonate fuel cell including a plurality of stacked unit cells 8, and separator plates 3 interposed between the adjacent unit cells, the respective unit cells having porous fuel electrode plates 9a and 9b, air electrode plates 11a and 11b, and electrolyte plates 10 interposed between these electrode plates; wherein the separator plate 3 forming a body 1 of the unit cell 8 is provided with at a center thereof intake internal manifolds 12a and 13a arranged at regular intervals for taking in fuel gas R and oxidant gas O towards a center of the body, and at both sides thereof exhaust internal manifolds 12b, 12c, 13b and 13c for exhausting the reacted fuel gas R and the reacted oxidant gas O, as well as forming passages for the fuel gas R ad the oxidant gas O at both sides thereof.
