Abstract

Fuel cell consists of an electrolyte, which connected to the anode and cathode through a polyelectrolyte membrane in which the membrane is capable of delivering protons from the anode toward the cathode. The aim of this study is to know the effect of acid on the membrane composite phosphotungstic chitosan/montmorillonite-silane 10% of the ion exchange capacity, proton conductivity and methanol permeability using a variation of the 0; 0.5; 1.0; 1.5%, respectively. The additions of phosphotungstic acid increased the proton conductivity and ion exchange capacity. However, in this study, the highest proton conductivity on chitosan/ montmorillonite-silane 10%/1.0% phosphotungstic acid caused by a strong hydrophilic nature phosphotungstic acid.

Abstract

Chitosan; calcium carbonate; DMFC; thermal stability Membrane is the most important part of Direct Methanol Fuel Cell (DMFC) because of its function as a proton transfer. The purpose of this research was studying the effect of calcium carbonate filler to the performance of chitosan (CS)/Calcium Carbonate (CC) composite membrane using 0.02; 0.04; 0.06; 0.08; and 0.10 g of CC. In this study, CS/CC membranes showed high performance for DMFC application. The best concentration of CS/CC was obtained with 0.06 g of CC based on proton conductivity, methanol permeability, and TGA measurements.

Abstract

Membrane CS/MMT-GA were synthesized by inversion phase method. In this study, CS as matrix, MMT as filler and GA as cross linking agent. CS-GA-MMT showed high performance as good candidate for DMFC. The best composition was obtained to CS/MMT-GA2 with highest proton conductivity and lower methanol permeability.
