摘要

Direct methanol fuel cells (DMFCs) technology is considered promising for green and efficient power generation. However, a major limitation of DMFCs is methanol crossover from the anode to the cathode. Herein, a phosphoric acid-imbibed polyacrylamide (PAM)/Nafion~® composite membrane, a semi-interpenetrating polymer network was investigated for its potential use as an efficient proton exchange membrane for DMFC application. The extraordinary ability of the PAM/Nafion~® composite membrane to absorb a large quantity of aqueous solution was exploited to achieve a high phosphoric acid loading, for the generation of membranes with high proton conductivity. The PAM/Nafion~® composite membrane also exhibited excellent acid retention and high humidity with a comparatively low methanol crossover, which are very important prerequisites for the DMFC application. The surface morphologies and cross-section of the prepared PAM/Nafion~® composite membrane were observed via optical microscopy and scanning electron microscopy (SEM). Thermogravimetric analysis (TGA) demonstrated improved thermal properties of the prepared membranes. Based on performance, in conjunction with the low-cost synthesis approach, the new membrane was deemed feasible for use in DMFCs.
