已经研究了使用多壁碳纳米管作为质子交换膜燃料电池的铂载体作为通过增加铂的利用来降低燃料电池的成本的方式。采用化学气相沉积法在碳纸上直接选择性生长碳纳米管，电沉积钴催化碳纳米管的生长。所制备的碳纳米管被用作随后的铂催化剂的载体，铂催化剂被电沉积在碳纳米管上。通过物理化学和电化学表征，确定了钴、碳纳米管和在碳纳米管上电沉积铂的形貌。证明了使用碳纳米管基电极的燃料电池的可行性。
The use of multiwalled carbon nanotubes as a platinum support for proton exchange membrane fuel cells has been investigated as a way to reduce the cost of fuel cells through an increased utilization of platinum. Carbon nanotubes were selectively grown directly on the carbon paper by chemical vapor deposition with electrodeposited cobalt catalyzing the growth of the carbon nanotubes. The as-prepared carbon nanotubes were employed as the support for the subsequent platinum catalyst, which is electrodeposited on the carbon nanotubes. Physicochemical and electrochemical characterizations were conducted to identify the morphologies of the cobalt, the carbon nanotubes, and the electrodeposited platinum on the carbon nanotubes. The feasibility of a fuel cell using the carbon nanotube-based electrodes was demonstrated.
