| 摘要 |
A nano-patterned membrane electrode assembly (MEA) is provided, which includes an electrolyte membrane layer having a three-dimensional close-packed array of hexagonal-pyramids, a first porous electrode layer, disposed on a top surface of the electrolyte membrane layer that conforms to a top surface-shape of the three-dimensional close-packed array of hexagonal-pyramids, and a second porous electrode layer disposed on a bottom surface of said electrolyte membrane layer that conforms to a bottom surface-shape of the three-dimensional close-packed array of hexagonal-pyramids, where a freestanding nano-patterned MEA is provided.
