A tank device for temperature pressure relief in a fuel cell tank, the tank device comprising at least two tank containers and a supply line which can be connected to the tank containers, each of the at least two tank containers having at least one shutoff valve at one end, the shutoff valve being arranged between the respective tank container and the supply line. At least one safety valve is arranged at another end of the tank container, wherein at least the at least two tank containers and the respective safety valve are at least almost completely enclosed by a housing element and/or are encapsulated from an environment. A positive pressure prevails in the housing element, wherein the housing element contains a temperature-sensitive material, wherein the meltable medium of the safety valve melts when the pressure prevailing in the inner space falls, and thus opens the safety valve.
