Method for operating a fuel gas tank system, and control device

Abstract

The invention relates to a method for operating a fuel gas tank system (1) with a plurality of fuel gas tanks (2) connected in parallel for storing fuel gas, preferably hydrogen, in which method, in order to avoid local freezing during the removal of fuel gas from a fuel gas tank (2), the temperature in the fuel gas tank (2) and/or in a removal path (4) which is connected to the fuel gas tank (2), in particular in the region of at least one functionally relevant component (3), is monitored and, if the temperature falls below a predefined lower limit value T_ref, (a) the removal from the fuel gas tank (2) is stopped and a switchover is carried out to another fuel gas tank (2), and/or (b) heat is fed in a targeted manner to the removal path (4) and/or the at least one functionally relevant component (3). The invention also relates to a control device for carrying out steps of the method.
