Round 1

Reviewer 1 Report

This study contains a new setup to evaluate water uptake/transport within PFSA membranes. This work is original, well-reference and valuable to practical operation of PEMFCs and electrolysers

Dear Reviwers 

Thank you so much for your consideration

Reviewer 2 Report

In this manuscript, an experimental configuration is designed to investigate the diffusion mechanism of water through the membrane in PEMFC applications. A flat membrane module is tested in an isothermal test chamber to test the influence of temperature on the water absorption and transport characteristics of Nafion 117 and Nafion 211 membranes. The results indicate that the water content of Nafion 211 is higher than that of Nafion 117. The water content and diffusion coefficient are proportional to the operating temperature.

I consider the content of this manuscript will definitely meet the reading interests of the readers of the Polymers journal. I suggest giving a minor revision and the authors need to clarify some issues or supply some more data to enrich the content.
