Developing a new strategy to retain phosphoric acid (PA) to improve the performance and durability of high‐temperature proton exchange membrane fuel cell (HT‐PEMFC) remains a challenge. Here, a strategy for ion‐restricted catcher microstructure that incorporates PA‐doped multi‐quaternized poly(fluorene alkylene‐co‐biphenyl alkylene) (PFBA) bearing confined nanochannels is reported. Dynamic analysis...
Biomass‐based energy storage devices (BESDs) have drawn much attention to substitute traditional electronic devices based on petroleum or synthetic chemical materials for the advantages of biodegradability, biocompatibility, and low cost. However, most of the BESDs are almost made of reconstructed plant materials and exogenous chemical additives which constrain the autonomous and widespread advantages...
