  • Patent number: 10026975
    Abstract: Each of a plurality of layered power generation elements (2) of a fuel cell (1) is provided with a plate-shaped cell (10), an anode plate (30), and a cathode plate (20). The anode plate (30) has a fuel intake manifold (4), a plurality of first gas channels (35), and a second gas channel (61). A restricting part (80) for restricting the fuel gas, which flows from the fuel intake manifold (4) through the gas inlet (38) into the second gas channel (61), from flowing into the first gas channel (35) is provided along the surface, opposite the gas inlet (38), of the second gas channel (61).

  • Publication number: 20170040620
    Abstract: In a fuel cell provided herein, the flow resistance of oxidant gas and that of oxidant off-gas in a cell stack are low to effectively reduce risk of gas leakage and risk of resultant destructive damage. The fuel cell comprises a cell stack 10 configured by stacking an anode plate 12 and a cathode plate 13 alternately. A fuel-containing gas intake manifold 10F is formed integrally on one of two sides of the cell stack 10 facing each other. A fuel off-gas exhaust manifold 10G is formed integrally on the other of these two sides. An oxidant gas intake manifold 10H is formed integrally on one of different two sides facing each other. A manifold is not formed on the other of the different two sides to form an exhaust port 15b on a lateral side of the cell stack 10 through which oxidant off-gas.

  • Publication number: 20160204452
    Abstract: Each of power-generating elements 2 stacked on top of each other includes a plate-like cell 10, an anode plate 30, and a cathode plate 50. The cathode plate 50 includes a plurality of first gas passages 58 which extend from an end portion of the cell 10 to an opposite end portion of the cell 10, and a plurality of second gas passages 61 which are sandwiched between the first gas passages 58 and the cell 10, which extend in a direction intersecting an extending direction of the first gas passages 58, which are exposed toward the cell, and each of which communicates with at least two of the first gas passages 58 in a vicinity of an intersection in a direction in which the cathode plate is stacked.

  • Publication number: 20150255812
    Abstract: A fuel cell 1 includes a plurality of power-generating elements 2 stacked together. The power-generating element 2 has a planar cell 10, an anode plate 30, and a cathode plate 20. The anode plate 30 has a fuel supply manifold 4, a plurality of first gas passages 35, and a second gas passage 61. A restricting portion 80 is arranged along an opposed surface of the second gas passage 61, the opposed surface facing the gas intake 38, so as to restrict flowing of the fuel gas toward the first gas passages 35 into the second gas passage 61.
