The invention relates to a tank device (1) for thermal pressure relief of a fuel cell tank, the tank device (1) comprising at least two tank containers (2) and a supply line (4) that can be connected to the tank containers (2), each of the at least two tank containers (2) having at least one shut-off valve (8) at one end (20), the shut-off valve (8) is arranged between the corresponding tank container (2) and the supply line (4). According to the invention, at least one safety valve (10) is arranged on the other end (21) of the tank container (2), at least the at least two tank containers (2) and the corresponding safety valve (10) being at least almost completely surrounded by a housing element (24) and/or sealed in particular in a pressure-tight manner with respect to the surroundings (190). In this case, an overpressure (181), in particular with respect to the surroundings (190) and/or with respect to a surroundings pressure (191), is present in the housing element (24), in particular in the interior (180), the housing element (24) having a temperature-sensitive material (25), in particular plastic, and the safety valve (10) opens in the event of a drop in the pressure, in particular the overpressure (181), present in the interior (180).
本发明涉及一种用于燃料电池箱的热压力卸载的箱设备(1),其中,所述箱设备(1)包括至少两个箱容器(2)和能够与所述箱容器(2)连接的供应管路(4),其中,所述至少两个箱容器(2)中的每个箱容器在一端部(20)上具有至少一个截止阀(8),所述截止阀(8)布置在对应的箱容器(2)和所述供应管路(4)之间。根据本发明,在该箱容器(2)的另一端部(21)上布置有至少一个安全阀(10),其中,至少所述至少两个箱容器(2)和对应的安全阀(10)至少几乎完全被壳体元件(24)包围和/或相对于周围环境(190)尤其压力密封地封装。在此,在所述壳体元件(24)、尤其内部空间(180)中存在尤其相对于周围环境(190)和/或相对于周围环境压力(191)的过压(181),其中,所述壳体元件(24)具有温度敏感的材料(25)、尤其是塑料,其中,所述安全阀(10)在所述内部空间(180)中存在的压力、尤其是过压(181)下降的情况下打开。
