Problems solved by technology

[0002] During the assembly process of current fuel cells, the pin holes on the pole plate are usually used to coordinate with the pins for positioning. For fuel cells with high power, the size of the pin holes used for positioning will be large, which will affect the structural strength of the pole plate, effective The area utilization rate has a great influence. At the same time, after the plate assembly is completed, due to the assembly error of each assembly device, the pins may not be removed smoothly, which affects the assembly efficiency of the fuel cell.
[0003] On the other hand, CVP (battery voltage acquisition device) usually requires a separate raised structure on the plate, which also increases the complexity of plate assembly

Embodiment Construction

[0030] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0031] The following will refer to Figure 1-Figure 8 The pole plate 1 of the present invention will be described in detail in conjunction with the embodiments.

[0032] refer to Figure 1-Figure 5 As shown, the edge of the pole plate 1 according to the embodiment of the present invention is provided with a plurality of open gaps, wherein at least a part of the gaps are positioning gaps, and the positioning gaps are arranged on the edge of the pole plate 1 to help improve the effective area utilization rate of the pole plate 1, At the same time, when the structure or dimension design of the positioning notch is changed, the positioning notch located at the edge of the pole plate 1 has less impact on the function of the pole plate 1 , which is beneficial to save the development and design cycle.

Abstract

The invention discloses a polar plate, a fuel cell and an assembly method of the fuel cell. A plurality of open notches are formed in the edge of the polar plate, at least one part of the notches are positioning notches, and the positioning notches are positioned on corresponding positioning elements from the open positions. According to the polar plate, the positioning notches are formed in the edge of the polar plate, the influence of the positioning notches on the polar plate is reduced, the effective area utilization rate of the polar plate is improved, the position precision of polar plate assembly is improved due to the arrangement of the multiple positioning notches, and the open positioning notches facilitate disassembly of positioning elements after polar plate assembly is completed; the assembling efficiency of the polar plate is improved.
