Three-dimensionally structured electrode assembly for proton-exchange membrane fuel cell based on patterned and aligned carbon nanotubes

摘要

With the recent advancement in nanotechnology,carbon nanotubes (CNTs) have demonstrated great promise in various commercial applications [1,2].Novel catalyst supports for proton-exchange membrane fuel cells (PEM-FCs) is one of such examples.The desirable attributes of CNTs include their unique geometric shape,high surface area,stability in the fuel cell environment and excellent mechanical and electrical properties.
