质子交换膜燃料电池用膜材料的性能表征

Membrane Characterizations of Proton Exchange Membrane Fuel Cell

质子交换膜 (PEM)是质子交换膜燃料电池 (PEMFC)的关键组件之一 ,其性能的好坏在很大程度上决定了PEMFC的性能。本文对PEMFC膜材料的性能表征进行了综述 ,讨论了膜材料的孔隙率、密度、粘度、磺化率、稳定性。

Proton exchange membrane(PEM) is one of the key parts of the proton e xchange membrane fuel cell(PEMFC); its properties determine the main properties of the PEMFC in the great sense. This paper reviews the characterization of the membrane material; and discusses the characterization of porosity, density, vis cosity, sulfonation, selective permeation, conductivity and so on.
