Abstract

A new membrane was synthesized containing pure alginate, crosslinking agent (CaCl2), and plasticizer (glycerol). Characterization studies of the membrane were applied to determine the characteristics and morphology using field emission scanning electron microscope, EDX, FTIR, XRD, and atomic force microscopy analysis. The half-cell performance test of the membrane was verified by several tests, including proton conductivity and methanol permeability. The best membrane had high proton conductivity (10.1 × 10−3 S cm−1) and very low methanol permeability (1.984 × 10−7 cm2 s−1), which consequently resulted in very high selectivity (5.0907 × 104 Ss cm−3). Glycerol had a positive modification and good influence on the alginate characteristics. Furthermore, the poor mechanical properties of the alginate biopolymer were enhanced by calcium chloride and glycerol inside the polymer.
