摘要：

The development of proton exchange membrane fuel cells(PEMFCs)that operate over a wide temperature range without additional humidificationsystems remains challenging. In this work, wide-temperature-rangeproton exchange membranes (PEMs) were constructed from novel Tro''ger'sbase (TB)-based intrinsically microporous copolyimides (co-PIs) finelyadjusted by incorporating crown ether units into chain backbones.Owing to the strong siphoning effect of existing microporosity andhydrogen bonds or the acid-base interactions of crown etherand TB units with phosphoric acid (PA) and/or H2O, thePA-doped co-...
