The invention provides a cooling system for an electric vehicle having a fuel cell. The cooling system comprises: at least one first circuit designed as a compact cooling unit and having at least one indirect evaporator and at least one indirect condenser; at least one second circuit which is designed as a cryogenic circuit and has at least one first partial circuit for cooling electronic components provided for controlling the fuel cell, at least one second partial circuit for cooling electronic components of the electric drive system, and at least one third partial circuit passing through the indirect condenser; at least one third circuit provided for cooling the at least one battery; at least one fourth circuit flowing around the fuel cell and designed as a high-temperature circuit, and a control device, in which a number of pumps driving the flow of liquid in the circuit and a number of controllable valves controlling the flow of liquid in the secondary circuit are arranged in the system, wherein the second circuit and the third circuit are connected to each other by means of a first controllable valve provided as the only control valve in the second circuit. Furthermore, a vehicle having a cooling system and a method for controlling a cooling system are provided.
