The device comprises a shell 1, a connecting frame 2, a beam 3, a first pile module 4, a second pile module 5, a first end plate 6, a second end plate 7, a pressing bar 8, connecting strips 9, a back plate 10, a face plate 11, a limiting pin 12, a spring sleeve 13, an operation window 14 and a side plate 15.

Detailed Description

The following description of the embodiments of the utility model refers to the accompanying drawings, in which: as shown in fig. 1 to 5, a dual-module fuel cell stack includes a casing 1 having a cube shape, one side of the casing 1 is provided with an opening, a connection frame 2 is provided at the opening, a cross beam 3 is provided at the middle of the connection frame 2,

The working process of the dual-mode fuel cell stack of the embodiment of the utility model is as follows: because the middle part of the connecting frame 2 arranged at the opening of the shell 1 is provided with the cross beam 3, a structure similar to a Chinese character 'ri' is formed, namely, two openings of an upper opening and a lower opening are arranged on the connecting frame 2,

When the first electric pile module 4 and the second electric pile module 5 are required to be packaged into the shell 1 at the same time, the first electric pile module 4 is inserted into the upper opening, the second electric pile module 5 is inserted into the lower opening, then the operation is carried out through the operation window 14, the connecting strip 9 is installed between the back plates of the two electric pile modules, the two electric pile modules are continuously pressed into the shell 1 after being installed, after being pressed into place, one end of the limiting pin 12 is inserted into the limiting hole formed on the back plate 10, the other end of the limiting pin 12 is inserted into the limiting hole formed on the inner side of the panel 11 in advance, the two electric pile modules realize limiting and positioning under the action of the limiting pin 12,
