Alginate Modified Biomaterial Membranes for Fuel Cells Applications
Sodium alginate was employed in this research to develop pioneering polymer membranes for potential use as an electrolyte in proton exchange membrane fuel cells. Various reagents were employed to modify the membranes, such as ionic liquids, zirconium phosphate, zeolite nanoparticles, glycerol, and deep eutectic solvents. Deep eutectic solvents used in the present study are synthesized at the laboratory using benign, inexpensive, and environmentally neutral precursors, such as choline chloride, glycerol, ethylene glycol, and fructose. Modification of the sodium alginate membranes was done to enhance its proton conductive capabilities and machinal strengths. Of the tested reagents, fructose-based deep eutectic solvent and glycerol gave the highest proton conductivity. Both reagents enhanced two orders of magnitude of proton conductivity, and the new values obtained are 6.1×10−5S/cm and 6.5×10−5S/cm. Fructose-based deep eutectic solvent; however, compromised the mechanical properties of the polymer matrix, therefore, it requires further testing. Future work will be dedicated to the characterizations of the best membranes using attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy, thermogravimetric analysis (TGA), and the membrane's water uptake capacities.
