Abstract

In this study, chitosan (Chi), alginate (Alg), and mesoporous phosphotungstic acid (mPTA) were used as electrolyte membrane materials for DMFC. Chi and Alg will be crosslinked with mPTA filler to improve the performance of the electrolyte membrane. Characterizations carried out include tensile tests, methanol permeability, and proton conductivity. The results of the tensile test showed that the Chi-Alg(3:1) membrane had a higher tensile strength value (26.64 N/mm² ) than the pure chitosan membrane (11.97 N/mm² ). The results of methanol permeability show that the Chi-Alg(3:1)/mPTA(0.20%) membrane has a lower methanol permeability value (8.17×10^–6 cm² s^–1 ) and a relatively high proton conductivity value (45.8×10^–3 S cm^–1 ). Chi-Alg/mPTA membrane, simplicity of the used simple preparation method, and the cost reduction can be applied as an electrolyte membrane for DMFC.
