Researchers unveil fuel cell membrane that moves protons 6.5 times faster

As of September 2026: Leading the research team behind the new membrane

Chinese researchers at the Beijing Institute of Technology have built a fuel cell membrane that moves protons 6.5 times faster than today's designs and cuts the energy barrier by more than half. In tests the cell produced 0.75 watts per square centimeter at 0.7 volts, about four times the power of conventional membranes.
