Phosphorylated Zeolite-A/Chitosan Composites as Proton Exchange Membrane Fuel Cell
Phosphorylated zeolite-A/chitosan composites were prepared and characterized as an alternative material for proton exchange membrane fuel cell (PEMFC). Their applicability was demonstrated by mechanical properties, swelling property, proton conductivity, methanol permeability, and thermal resistance. Chitosan was prepared from shrimp shell waste by deproteination, demineralization, and deacetylation. Chitosan was modified using zeolite A in the various concentrations.
