A bipolar plate for a fuel cell stack of a fuel cell system is described, having at least one main duct portion, which is designed for feeding a fluid (R1, R2, K); a plurality of inflow duct portions that branch off the main duct portion; a plurality of distribution duct portions fluidically connected to the inflow duct portions. The inflow duct portions are arranged along at least a part of the circumferential contour of the main duct portion such that each inflow duct portion, with regard to an imaginary orthogonal, in a respective connecting region of the inflow duct portion and main duct portion, to the circumferential contour at that location, is inclined with respect to this orthogonal such that, between the orthogonal and an inflow duct axis, an angle of incidence is formed, wherein, on the basis of the inclined arrangement of the inflow duct portions, a swirling flow for the fluid flowing in is able to be generated in the main duct portion.
