Proton Exchange Membrane Fuel Cell (PEMFC) is fuel cells that utilize membrane as the electrolyte. The electrolyte membrane was synthesized utilizing the natural polymer chitosan modified into hybrid zeolite A chitosan sulfonated membrane. The objective of the research are to synthesize hybrid zeolite A chitosan sulfonated membrane for PEMFC with a variations of zeolite concentration range 0, 40, 50, 60, 70, 80% (w/w) and to determine the ability of a polymer electrolyte membrane for PEMFC. Preparation of the membrane initially by blending chitosan solution with zeolite then immersed with H2SO4 0.36 N. Morphological of zeolite A was characterized by XRD and performance of the membrane was characterized by FTIR and SEM. The diffractogram of zeolite A synthesized appeared 2θ 13.98; 24.05; 32.59; 35.79; 38.03; 43.58º and the FTIR spectra of synthesized hybrid zeolite A chitosan sulfonated membrane showed at 3448.49 cm-1 for hydroxyl functional group, 1648 cm-1 and 1565 cm-1 for amide I dan amide II which is directly decrease with the addition of zeolite concentration. Hydrogen bonds between the Si-O from zeolite A–chitosan bonding showed at 1040 cm-1 and 455.14 cm-1. The S-O bonding from sulfonate functional group showed at 619.12 cm-1. The ability of the membrane as the electrolyte membrane showed the high mechanical properties Modulus Young 5.07 × 107 N/m2, water swelling test 61.38%, ion exchange capacity test with acid-base titration method is obtained IEC (Ion Exchange Capacity) 1.0107 meq/g, proton conductivity test with EIS (Electrochemical Impedance Spectroscopy) method is 2.2 x ×10-4 S/cm, and the methanol permeability test with dead-end method 1.26 kg/m2hour. This characteristic showed that the hybrid zeolite A chitosan sulfonated membrane potential as proton exchange membrane to be applied to the PEMFC.
