This review discusses the progress of research on sulfonated poly(ether ether ketone) (SPEEK) and its composite membranes in proton exchange membrane fuel cells (PEMFCs). SPEEK is a promising material for replacing traditional perfluorosulfonic acid due to excellent thermal stability, mechanical property, tunable conductivity. By adjusting degree sulfonation (DS) SPEEK, hydrophilicity conductivity can be controlled, while also balancing mechanical, thermal, chemical stability. Researchers have developed various by combining with range organic inorganic materials, such as polybenzimidazole (PBI), fluoropolymers, silica, enhance chemical, stability membranes, reducing permeability improving overall performance cell. Despite significant potential PEMFCs, there are still challenges room improvement, including conductivity, cost-effectiveness, environmental impact assessments.
