Specifically, the method for building the bipolar plate model strength simulation model comprises the following steps:
s100: and acquiring the three-dimensional model.
As shown in fig. 2 and 3, the three-dimensional model includes a cathode plate 14 and an anode plate 13 arranged at intervals, a bipolar plate 11 arranged between the cathode plate 14 and the anode plate 13, an MEA (Membrane Electrode Assembly) 12 arranged between the bipolar plate 11 and the anode plate 13, and another MEA12 arranged between the bipolar plate 11 and the cathode plate 14, wherein the MEA12 includes an MEA121, a plurality of sealing rings 122, and a film 123 connecting the plurality of sealing rings 122.

Wherein, the three-dimensional model is imported into simulation analysis software, such as finite elements, and a corresponding basic simulation model can be produced. The final bipolar plate model strength simulation model can be obtained by setting the basic simulation model in simulation software.
It should be noted that the bipolar plate model strength simulation model in the present embodiment is used to calculate the strength of the bipolar plate 11, and therefore, the bipolar plate model 21 should be consistent with the three-dimensional structure of the bipolar plate 11 to ensure accurate results.
S300: the cathode plate model 24 and the anode plate model 23 are set as rigid bodies.
When the bipolar plate model strength simulation model is subjected to calculation and analysis, the cathode plate model 24 needs to be fixed, the anode plate model 23 needs to be pressed downwards, and after all the part models are sequentially pressed, whether the strength of the bipolar plate model 21 meets the requirement is evaluated. It follows that the anode plate model 23 and the cathode plate model 24 are used only for the transmission of force, so that the anode plate model 23 and the cathode plate model 24 can be set as rigid bodies and the degrees of freedom of the mesh of the rigid bodies are not considered in the process of computational analysis.

Wherein, the simplification processing of the MEA component model comprises the following steps:
s401: the film model is removed.
The MEA assembly model is shown in figure 4 with the film removal model removed.
S402: the cross section of the seal ring mold 222 is adjusted to a rectangular cross section.
As shown in fig. 5 and 6, it is noted that, in the three-dimensional model, the cross section of the gasket 122 before elastic deformation is a circular cross section, and when the respective parts between the anode plate 13 and the cathode plate 14 are pressed against each other, the gasket 122 is elastically compressed, and at this time, the cross section thereof is irregularly shaped, and one surface of the gasket 122 is in surface contact with the bipolar plate 11 and the other surface is in surface contact with the anode plate 13 or the cathode plate 14. The section of the seal ring model 222 is adjusted to be a rectangular section, so that the scale of the model can be simplified, and the height of the seal ring model 222 is compressed and the width of the seal ring model is not changed by the extrusion of the models on the two sides of the seal ring model in the simulation process, which is different from the material object of the seal ring 122.
Wherein, the diameter of the circular section is D, the height of the rectangular section is D, and the height direction refers to the spacing direction of the cathode plate model 24 and the anode plate model 23. Therefore, the compression amount of the sealing ring 122 can be kept unchanged in the simulation calculation process. Further, the width of the sealing ring 122 after being pressed by the bipolar plate 11 and the cathode plate 14, or the width of the sealing ring 122 after being pressed by the bipolar plate 11 and the anode plate 13 is L, and the width of the rectangular cross section is L. With such an arrangement, the width of the rectangular section of the sealing ring model 222 is consistent with the width of the extruded real object, so that the final effect is consistent when the simulation force is transmitted, and the accuracy of the simulation calculation result is further ensured. The width dimension of the sealing ring 122 pressed by the bipolar plate 11 and the cathode plate 14, or the width dimension of the sealing ring 122 pressed by the bipolar plate 11 and the anode plate 13 can be obtained through experimental measurement.
S403: the seal ring model 222 is a non-linear elastic material constitutive model.
The seal ring model 222 is a non-linear elastic material constitutive model, and can be used for fitting a real force transmission process when the seal ring 122 is compressed, so that an accurate calculation result is ensured.
S404: the MEA model 221 employs a non-linear elastic material constitutive model.
