Proton Exchange Membrane Fuel Cells (PEMFC) are low temperature operating fuel cells that fit many civilian and military applications. Carbon Nano Tube (CNT) have been explored as carbon support materials for catalysts due of their unique properties, i.e., high specific surface area, high adsorption capacity and high electronic conduction all of which fit to the requirements of the PEMFC electrode. CNT have an advantage over commonly used Carbon Black (CB), due to its ability utilize as catalyst support without the CB disadvantages (low cell stability and decrease of platinum (Pt) utility).
This technology suggests the usage of the state of the art technology for manufacturing CNT as a support for deposited Pt particles in order to achieve enhanced catalytic activity, lower Pt content and ultimately used in cost-effective PEMFC. Pt particles were deposited onto CNTM in a simple, inexpensive and easy to control process. CNT has good adhesion to Nafion™ and therefore allows building a standard structure of PEMFC with CNT.
