Abstract

One of the key issues in the DMFC framework is methanol crossover. Surface modification is a promising approach to problem solving. A SPEEK/cloisite nanocomposite membrane exfoliated by electrospun is developed in this research. The membrane is prepared by immersing electrospun SPEEK/cloisite fibers mats in the SPEEK polymer matrix, which is half-solidated. The research addresses the effect of exfoliated morphology on the productivity of membranes. Compared to other sampling membranes like Nafion® 117, SP/e-spunCL15 with a completely exfoliated configuration has the best efficiency with a current density of 7.73 mAcm-2 and a power density of 1.18 mWcm-2. Improved morphological, dimensional change properties and performance assign a well dispersed cloisite15A induced by the electrospinning technique to the membranes more effective for direct methanol fuel cell applications.
