[求助] PEMFC燃料电池浓度过电势与催化层结构的关系

审稿人给出的一条意见:“The optimized pore structures in the catalyst layers are effective to reduce the mass transport losses. However, large pore structures generally have negative aspects that the proton conductivity is reduced and the electrical resistance is increased. The cell performance was varied depending on the various losses caused by ohmic, activation and concentration overpotentials.the authors should demonstrate detailed reasons why the pore structures in the catalyst layers reduced the overpotentials, and thereby enhanced the cell performance.”
    文章中有EIS图谱,请问是要综合欧姆阻抗和活化阻抗对电池性能的影响吗?还是从其它的角度进行解释? 此外,concentration overpotentials方面如何进行阐释?
    非常感谢!
