Separator for molten carbonate fuel cell

摘要

Disclosed herein is a separator for a molten carbonate fuel cell, the separator including four steel sheets in which edges of the four steel sheets are joined to each other thereby providing three spaces therebetween, comprising a cathode channel, serving as a flow path of oxidant gas, formed in the first space; an anode channel, serving as a flow path of fuel gas, formed in the second space such that the anode channel is separated from the cathode channel; and a fuel gas reforming channel formed in the third space, which is located between the first space and the second space. The separator for a molten carbonate fuel cell is advantageous in that the volume of the fuel cell is decreased, and the structure thereof is simple, thus reducing the production cost thereof.

1. A separator for a molten carbonate fuel cell, the separator including four steel sheets in which edges of the four steel sheets are joined to each other thereby providing three spaces therebetween, comprising:
a cathode channel formed between two of the four steel sheets, serving as a flow path of oxidant gas to be reduced with a cathode in the cathode channel, and formed in a first space; an anode channel formed between two of the four steel sheets, serving as a flow path of fuel gas, and formed in a second space such that the anode channel is separated from the cathode channel; a fuel gas reforming channel formed between two of the four steel sheets, and formed in a third space located between the first space and the second space; an oxidant gas inlet manifold for introducing the oxidant gas into the cathode channel; an oxidant gas outlet manifold for discharging the oxidant gas from the cathode channel; a fuel gas inlet manifold for introducing the fuel gas into the fuel gas reforming channel; a fuel gas outlet manifold for discharging the fuel gas from the anode channel; and a reformed gas exchange manifold for carrying the fuel gas from the fuel gas reforming channel to the anode channel wherein the oxidant gas inlet manifold, the oxidant gas outlet manifold, the fuel gas inlet manifold, the fuel gas outlet manifold and the reformed gas exchange manifold are formed in a border of the separator, and the oxidant gas inlet manifold and the fuel gas outlet manifold are formed on one side of the border and disposed horizontally separated from each other so as not to vertically correspond to each other at the one side of the border.
