Embodiment Construction
[0021] Such as figure 2 with image 3 As shown, the direct-flow low-temperature low-pressure rectangular fuel cell of this embodiment includes an intake pipe connecting plate 3 located above and an exhaust pipe connecting plate 4 located below. Press tightly with at least two pieces ( figure 1 Only two) carbon plates 1 distributed in parallel up and down are shown in the figure, and an exchange membrane 2 is sandwiched between every two adjacent carbon plates 1, and the upper surface and the lower surface of each carbon plate 1 are A plurality of channels 1-1 parallel to each other are formed, and the channels 1-1 are used as gas flow channels for gas circulation.
[0022] Eight bolt connection holes 5 are formed on the intake pipe connecting plate 3, the exhaust pipe connecting plate 4 and each carbon plate 1, so that they are connected together by bolts.
[0023] Compared with the traditional fuel cell, the biggest feature of the fuel cell in this embodiment is that the ...
