Abstract:
1. A nano-patterned membrane electrode assembly (MEA), comprising: a. an electrolyte membrane layer, wherein said electrolyte membrane layer comprises a three-dimensional close-packed array of hexagonal-pyramids; b. a first porous electrode layer, wherein said first porous electrode layer is disposed on a top surface of said electrolyte membrane layer and conforms to a top surface-shape of said three-dimensional close-packed array of hexagonal-pyramids; and c. a second porous electrode layer, wherein said second porous electrode layer is disposed on a bottom surface of said electrolyte membrane layer and conforms to a bottom surface-shape of said three-dimensional close-packed array of hexagonal-pyramids, wherein a freestanding nano-patterned MEA is provided.
