Peels of an onion: New composite proton exchange membranes prepared through layer-by-layer coating of a biopolymer has shown superior methanol barrier properties, while maintaining a high affinity to proton transfer same time. The highly selective skin layer in the composite system significantly increases the fuel utilization efficiency in direct methanol fuel cells (DMFCs).
