Novel fluoropolymer anion exchange membranes for alkaline direct methanol fuel cells

► A new kind of fluoropolymer anion exchange membrane was prepared. ► The membrane exhibited high ionic conductivity, good chemical, and thermal stability. ► The membrane was still intact after being hot-pressed at 2 MPa for 5 min at 50 °C. ► A maximum power density of 53.2 mW cm−2 of alkaline direct methanol fuel cell with the fluoropolymer membrane was achieved.
