Abstract
Due to higher oxygen vacancy concentration <graphic xmlns:xlink="http://www.w3.org/1999/xlink" id="ugt66" xlink:href="http://pubs.rsc.org/TA/2020/d0ta09397a/d0ta09397a-t66..gif"/> and trivalent lattice cerium concentration <graphic xmlns:xlink="http://www.w3.org/1999/xlink" id="ugt67" xlink:href="http://pubs.rsc.org/TA/2020/d0ta09397a/d0ta09397a-t67..gif"/>, ceria (CeO<sub>2−δ</sub>) incorporated Nafion film shows better durability (4.2 times) than pure Nafion film.
