This invention discloses a fuel cell and its application. The bipolar plate includes a connecting structure with a cross-flow channel and a narrowing structure. The hydraulic diameter of the narrowing structure is smaller than that of the non-narrowing structure. The non-narrowing structure of the flow channel has a connecting structure corresponding to at least one of two adjacent ridges. Furthermore, the resistance of the gas in the first direction through the narrowing structure is R1, and the resistance in the second direction through the connecting structure is R2, where R1 / R2 ≥ 20. The first direction is the flow direction of the gas entering the flow field, and the second direction is perpendicular to the first direction. Therefore, the fuel cell bipolar plate provided by this invention can more fully utilize the pressure drop generated by the narrowing structure to create a larger pressure difference between adjacent flow channels. This allows a smaller flow field pressure drop to create the same or higher level of under-ridge gas convection and permeation effect within the gas diffusion layer or membrane electrode, thereby improving the under-ridge mass transfer and drainage performance of the fuel cell.
