The paper contains interesting results and is worthy of publication, but a few moments need to be corrected to improve it. 1) The scheme in Fig. 1 does not fully correspond to the description of the experiment. In the text the acrylonitrile, acrylic acid, SPAK and EGDMA as cross-linker are used to synthesize the composite, while the scheme presents AN, acrylamide, SPAK and bisacrylamide. Please check. 2) Fig. 3 does not matches the text as well. The experiment description states: sol-gel system SG (TEOS or MAPTMS) – S1 - 0; S2 -1.0; S3 - 3.0; S4 - 5.0; S5 – 7.0. But Fig. 3b shows the results for MAPTMS fraction from 0 up to 10%. And Fig. 3a evidently should be TEOS fraction. Please check and correct. 3) PEMFC abbreviation needы to be deciphered.
