Use of Poly(styrene-<i>co</i>-acrylic Acid) in a Composite Ion-Solvating Membrane for Water Electrolysis.

ABSTRACT: Ion-solvating membranes (ISMs) have recently emerged as a promising class of materials for alkaline water electrolysis. Their non microporous polymer architecture and the absence of alkaline labile functional groups pave the way for a new generation of hybrid electrolyzers that combine the key features and advantages of conventional alkaline water electrolyzers (AWE) with those of proton exchange membrane water electrolyzers (PEMWE). Herein, a styrene-acrylic acid copolymer was synthesized and deposited onto a commercial microporous polypropylene support, yielding a composite ISM that couples an ion exchange capacity (IEC) of 2.72 mmol g^-1 with good mechanical properties (tensile strength of 65 MPa). The electrochemical performance of the membranes was evaluated by through-plane
