Comments and Suggestions for Authors
1. The abstract does not discuss the novelty and the results. Please revise the abstract properly.
2. Please merge Figures 4, 5, 6, and 7 into a single Figure in a two-row, two-column format for better illustration. Similarly, merge Figures 8 and 9, 10 and 11. merge Figure 13 to 15 in a single figure. Merge 16 to 19 in a single Figure. Similarly 20 to 23. Also 24 to 28. Accordingly, update the number of Figures in the main body of the manuscript.
The author may go through the following article for Figures and illustrations.
Ali, Y., Iqbal, N., & Lee, S. (2021). Inhomogeneous stress development at the multiparticle electrode of lithium‐ion batteries. International Journal of Energy Research, 45(10), 14788-14803.
2. No critical discussion is given to all the Figures. Please add the relevant technical discussion of each Figure. What the Figure represents. How the results vary and why they vary. What is the outcome?
3. Overall the paper is poorly written. Please revise the English properly.

Comments and Suggestions for Authors
The paper titled "Design and Implementation of High efficiency and Compact Fuel-Cell-Battery Hybrid Power System" presents a novel topology for a hybrid power system combining fuel cells and lithium batteries, aimed at enhancing efficiency and compactness while eliminating the need for DC/DC converters. The manuscript is clearly written and properly organized. I support the publication of the current form of this study after revisions of the following:
1. The authors present a detailed experimental setup and analysis. However, it would be beneficial to see a more comprehensive comparison with existing systems. This could include a wider range of operating conditions and a more detailed analysis of the system's performance under varying load conditions.
2. The technical aspects of the paper appear sound, with clear explanations of the operating principles, system architecture, and control methods. However, the paper would benefit from a more in-depth discussion of potential limitations or challenges associated with this new topology.
3. The claimed efficiency increase of 5.36% over traditional approaches is notable. However, the paper should address the robustness of these efficiency gains across a broader range of operating conditions and over extended periods.
4. The paper is generally well-organized and clearly written, but there are some areas where additional explanations or clarifications could be helpful, particularly for readers who may not be deeply familiar with the technical aspects of hybrid power systems.
5. The figures and diagrams are useful in understanding the proposed system. However, adding a few more illustrative diagrams comparing the proposed.

Comments and Suggestions for Authors
The authors propose a novel topology without DC/DC converter for a fuel cell-battery hybrid forklift system. The author conducted a large number of experiments and made effective analyses. But the author still needs to pay attention to some things to improve the quality of the article. See comments below.
