Abstract

A cathode supply (30) for a fuel cell (10) of a fuel cell unit (1) for a fuel cell system is provided, the cathode supply (30) including a cathode supply path (31) and a cathode exhaust gas path (32) and at least two fluid pumping devices (33, 133) for pumping a cathode operating medium (5) for the fuel cell (10) are fluido-mechanically coupled into the cathode supply path (31), at least one first fluid pumping device (133) of the at least two fluid pumping devices (33, 133) being drivable only on the basis of an enthalpy in a cathode exhaust gas (6) of the fuel cell (10). A fuel cell unit for a vehicle, in particular, an electric vehicle, a fuel cell system for a vehicle, in particular, an electric vehicle, or a vehicle in particular an electric vehicle, the fuel cell unit, the fuel cell system, or the vehicle including a cathode supply (30) is provided.
