- ... In operation of polymer electrolyte membrane fuel cell or direct methanol fuel cell, ·OH radicals are the major cause for the degradation of polymer electrolyte membrane. In order to enhance its antioxidation stability, cerium ion (Ce³⁺, CE), an ·OH radical quencher, is introduced to membrane, as it converts the ·OH radicals into inactive chemicals. In this study, aminoethyl‐15‐crown‐5 (CRE) is gr ...
