Bipolar plate for a fuel cell system

A bipolar plate (100) for a fuel cell system (1), the bipolar plate (100) comprising:

• a cathode-side plate (10), which on a first side (11) has a first channel structure (K1) for an oxygen-containing reactant (O2) and on a second side (12) has a second channel structure (K2) for a coolant (KM), and
• an anode-side plate (20), which on a first side (21) has a first channel structure (A1) for a fuel-containing reactant (H2) and on a second side (22) has a second channel structure (A2) for a coolant (KM),
• the cathode-side plate (10) and the anode-side plate (20) bearing against one another at the second sides (12, 22),
• wherein the first channel structure (K1) of the cathode-side plate (10) defines a shape and the second channel structure (K2) of the cathode-side plate (10) defines a shape that is different from the shape defined by the first channel structure (K1),
• wherein the first channel structure (K1) of the cathode-side plate (10) includes double and/or split-in-two channels (k1, k2) for the oxygen-containing reactant (O2),
• wherein the second channel structure (K2) of the cathode-side plate (10) has channels (km) for the coolant (KM),
• wherein when viewed along a line in a direction (R) transverse to and passing through the first channel structure (K1) and the second channel structure (K2), the double and/or split-in-two channels (k1, k2) are arranged next to one another before arriving at a channel (km) of the channels (km).
