Development of composite membranes for anion exchange membrane fuel cells
The objective is to prepare and characterize polymer-based composite membranes for anion exchange membrane fuel cells (AEMFCs) with high OH- conductivity, excellent mechanical properties, and good chemical stability. The effect of inorganic filler, cross-linker, and preparation techniques on properties and performance of composite anion exchange membranes (AEMs) are investigated. The chemical structures, morphology, thermal, and mechanical properties of AEMs are characterized by FTIR, SEM, thermogravimetric analysis, and universal testing machine, respectively. The performance of composite AEMs is verified using water uptake, swelling degree, ion-exchange capacity, and OH− conductivity measurement.
