ABSTRACT Membranes play a crucial role in Polymer Electrolyte Membrane Water Electrolysis (PEMWE), key technology for green hydrogen production. While perfluorosulfonic acid (PFSA) membranes are widely used commercial PEMWE systems, hydrocarbon‐based gaining attention due to concerns over fluorine emissions and potential future regulatory restrictions. However, challenges such as swelling dimensional instability must be addressed viable alternatives. In this study, poly(ether ether ketone) (PEEK) mesh modified PEEK (MPEEK) mesh, treated with oxygen molybdenum disulfide (MoS 2 ), were incorporated into sulfonated (SPEEK) matrix fabricate reinforced membranes. The structural integrity functional properties of the investigated. exhibited higher tensile strengths, SPEEK achieving 43.2 ± 1.6 MPa MPEEK reaching 48.9 1.5 MPa, compared 34.3 1.4 neat membrane. Although incorporation reinforcement layers led reduction proton conductivity SPEEK, decrease was less pronounced (42.5 mS/cm) than (40.12 mS/cm). This suggests that layer SPEEK‐MPEEK better preserves transport pathways, mitigating loss. Furthermore, oxidative stability tests using Fenton's reagent demonstrated 86.9% resistance degradation those reinforcement, attributed sulfide structures which effectively scavenged free radicals. These findings suggest offer promising alternative applications, combining enhanced mechanical strength, decreased ratio, superior stability.
