Imidazolium‐Quaternized Poly(2,6‐Dimethyl‐1,4‐Phenylene Oxide)/Zeolitic Imidazolate Framework‐67 (ImPPOZIF‐67) Composite Membranes for Methanol Fuel Cells

Journal of Applied Polymer Science, Volume 142, Issue 9, March 5, 2025.
ABSTRACT A membrane is the powerhouse of a fuel cell, and it is responsible for transport of ions from anode to cathode, thereby producing electricity in the process. In this work, a series of anion exchange membranes based on imidazolium‐quaternized poly(2,6‐dimethyl‐1,4‐phenylene oxide) (ImPPO) functionalized with different wt.% of zeolitic ...
