The invention relates to a method for operating a fuel cell system (10) of a motor vehicle (12), comprising at least one hydrogen tank (14), at least one fuel cell (18) which can be supplied with hydrogen from the hydrogen tank (14), and a cooling device (30) for cooling at least part of the fuel cell system (10), according to the invention, the energy consumption of the cooling device (30) is predicted as a function of a planned travel route of the motor vehicle (12), a future temporal pressure curve of the pressure present in the hydrogen tank (14) is predicted, and a future temporal energy curve of the heating energy is predicted, on the basis of which energy curves, the energy consumption of the cooling device (30) is determined. The heating energy is supplied by a cooling device (30) to the hydrogen tank (14) as a function of the predicted energy consumption in order to achieve a pressure curve.
