Effect of temperature on the mechanical performance of highly conductive composites for HT-PEMFC application

This study is a follow-up study of a previous study that examined the effect of temperature on the mechanical performance of the polymer carbon composite (CCP). In this study, the optimal formulation obtained from previous studies, was tried for use in polymer fuel cells of high temperature poly...
