摘   要：

This study introduces the relationship between physicochemical properties and blending time for two different clays, sepiolite nanofibers (SEP) and halloysite nanotubes (HNT) inside a Nafion matrix of electrolyte membrane used in a proton exchange membrane fuel cell (PEMFC). In the study, short blending time resulted in better homogeneity of Nafion/SEP and Nafion/HNT composite membranes, which displayed improved physicochemical properties compared with those of pristine Nafion membrane.
