Flow baffle for molten carbonate fuel cell

A fuel cell stack, comprising:

• a cathode input manifold adjacent to a cathode input side of the fuel cell stack;
• an anode input manifold adjacent to an anode input side of the fuel cell stack that is different from the cathode input side;
• a cathode output manifold adjacent to a cathode output side of the fuel cell stack that is different from the cathode input side and the anode input side;
• a fuel cell comprising:
• an anode comprising an anode inlet located on the anode input side of the fuel cell stack, an extended edge seal input chamber, and an anode active area, the anode inlet being in fluid communication with the anode input manifold, the extended edge seal input chamber being located on the cathode input side or the cathode output side, and the extended edge seal input chamber being in fluid communication with the anode inlet and the anode active area through an anode active area inlet, wherein the anode active area inlet is located on the cathode input side or the cathode output side;
• a cathode comprising a cathode inlet and a cathode active area, the cathode inlet being substantially parallel to the anode inlet;
• an electrolyte matrix layer separating the anode and the cathode;
• and
• an inlet baffle located adjacent to the anode active area inlet, the inlet baffle comprising a plurality of inlet baffle apertures at an inlet boundary between the extended edge seal input chamber and the anode inlet, at least a portion of the fluid communication between the extended edge seal input chamber and the anode inlet comprising fluid flow through the plurality of inlet baffle apertures, a length of the inlet baffle comprising at least 60% of a length of the inlet boundary, an average height of the inlet baffle comprising 100% or more of an average height along the inlet boundary, a combined cross-sectional area of the plurality of inlet baffle apertures comprising 0.5% to 6.0% of a total cross-sectional area at the inlet boundary.
