| Zusammenfassung: | The utility model relates to a bipolar plate, a fuel cell and an electrolytic bath, the bipolar plate comprises a plurality of flow channels with the same extension direction, a single flow channel comprises a plurality of flow channel units along the extension direction of the flow channels, the plurality of flow channel units are connected in sequence to form a bent flow channel structure, and each flow channel unit has a flow channel inclination angle; in the direction perpendicular to the extending direction of the flow channels, the flow channel inclination angles of every two adjacent flow channel units are beta 1 and beta 2 correspondingly, and beta 1 and beta 2 meet the following formula (I). According to the flow field area, the flow channel inclination angles of every two adjacent flow channel units are designed, then a plurality of flow channels are constructed, and then the flow field area is formed; the initial gas flow of each flow channel in the flow field area is the same, so that the reaction |
