ABSTRACT:
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 cells8, and separator plates3interposed between the adjacent unit cells, the respective unit cells having porous fuel electrode plates9aand9b, air electrode plates11aand11b, and electrolyte plates10interposed between these electrode plates; wherein the separator plate3forming a body1of the unit cell8is provided with at a center thereof intake internal manifolds12aand13aarranged 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 manifolds12b, 12c, 13band13cfor 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.
