Sulfonated poly(ether ether ketone) (SPEEK) membranes were used as support material for Nafion-SPEEK-Nafion (NSN) composite membranes. The NSN composite membrane was prepared by immersing the SPEEK in the Nafion-containing casting solution. The resulting composite membranes were mechanically durable
