Dual proton transport in Schiff base-modified chitosan functionalized with AMPS for fuel cell applications

Abstract Proton exchange membranes (PEMs) require high proton conductivity, stability, and durability for fuel cell applications. This study reports the synthesis of N-(2-acrylamido-2-methylpropane sulfonyl) chitosan (CSB) via Schiff base functionalization with 2-acrylamido-2-methylpropane sulfonic acid (AMPS) and the introduction of imine (–CH=N–) and sulfonic acid (–SO3H) groups, which significantly enhance dual proton conduction mechanisms through the […]

Incorporating of sulfo ethyl cellulose to augment the performance of sulfonated poly (ether ether ketone) composite for protonexchange membrane fuel cells

Composite membranes comprising sulfonated poly (ether ether ketone) (SPEEK) blended with varying proportions of sulfoethyl cellulose (SEC) at 5 wt% and 10 wt% were fabricated for fuel cell application. The structural, morphological, and thermal properties of these membranes were investigated using Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, and thermogravimetric analysis. The composite […]
