Abstract
Direct methanol fuel cell (DMFC) is considered as a highly efficient power source for portable devices. One of the main drawbacks of DMFC in practical application is methanol permeability through proton exchange membrane, which lowers down the cell performance.
In this study, layered zeolite MCM-22 was incorporated into Nafion solution to make composite membranes. The first part of my research is synthesis of MCM-22(P) and MCM-22. We also used inverse-micelle method to dispersive the layered structure of MCM-22(P) to make dis-MCM-22 then modified it by grafting and extraction. The second part of my research is preparation of composite membranes by solvent recasting technique. The influence of different treatments and amounts of MCM-22(P) was examined on the performances of resultant membranes in methanol permeability, proton conductivity and the test of DMFC.
The characterization of zeolite is by XRD, BET, SEM, TGA and FT-IR. The performance of membranes is tested by methanol diffusion, proton conductivity, SEM and DMFC experiments.
