Round 1

Reviewer 1 Report

1.The model should be described in more detail. Did the author verify the simulation results?

2.The pictures in the text should give the corresponding volume fraction range for the different colors.

3.Figure 3 should give a cloud map of the flow fraction of the other two flow fields.

4.In the section of introduction, I think there are other related references in this research field as follow:

1) .Lattice Boltzmann simulation of the structural degradation of a gas diffusion layer for a proton exchange membrane fuel cell. Journal of Power Sources, 2023, 556: 232452.

5.Some data formats need to be corrected, such as 0.5 m/s (page 4 line 159 and page 5 line 162).

6.The meanings of some symbols in Equation (2) are not given.

7.The conclusion section should be written even more concise.
