Abstract
A channel plate structure includes a nonreactive portion and an electrochemical reactive portion. The nonreactive portion includes at least one manifold inlet, at least one manifold outlet, flow channels, and cutoff structures. The cutoff structures are respectively disposed in the flow channels, and the ratio of the total area of the cutoff structures to the area of the channel plate structure is 0.002 to 0.01 based on battery size. Each of the cutoff structures includes a gas-liquid separation compartment, a joint portion, and a convergent portion, wherein a width of the joint portion is smaller than or equal to that of the gas-liquid separation compartment, the convergent portion connects the gas-liquid separation compartment to the joint portion, and the cross-sectional area of a flow path at an downstream end of the convergent portion is smaller than that of the flow path at an upstream end of the same.
