The molten carbonate fuel cell includes (a) an anode current collector (22) formed to be flat rectangular tubular and having a pair of outer surfaces each formed at the center thereof with a recessed portion (22a) for receiving an anode therein, the recessed portion being formed with a plurality of holes through which anode gas is supplied to anode from inside of the anode current collector, (b) a pair of cells (24) each disposed on each of the outer surfaces of the anode current collector, and (c) a pair of cathode current collectors (26) each cooperating with the anode current collector to sandwich each of the cells therebetween, the cathode current collectors being formed with a plurality of holes through which cathode gas is supplied to cathode from outside of the cathode current collector. The anode current collector, the cells and the cathode current collectors constitute a pair of independent parallel cells. The anode current collector (22) includes an anode gas passage (23a) which is connected to the anode current collector and through which an anode gas is to be provided to the inside of the anode current collector, and an anode current terminal (23b) formed at an end of the anode current collector perpendicular to the anode gas flow. Each of the cells includes an anode (24a) set in the recessed portion of the anode current collector, an electrolyte plate (24b) disposed in contact with an outer surface of the anode and extensive over the recessed portion of the anode current collector, and a cathode (24c) disposed in contact with an outer surface of the electrolyte plate. The cathode current collectors is connected to each other at ends disposed opposite to the anode current terminal to form &sqsup& shape, and the cathode current collector is formed at a connection point as a cathode current terminal. The above mentioned molten carbonate fuel cell makes it no longer necessary to use a separator for mechanically separating anode and cathode gases, resulting in remarkable cost down. |
