It is of great importance to significantly reduce Pt loading and consequently, the overall cost of fuel cells. Here we present a simple method of fabricating ultra low Pt loading electrodes for PEMFCs using ordered and porous vertically aligned carbon nanotubes as catalyst support. It is possible to substantially reduce the Pt loading by one order of magnitude by application of the new structured electrodes.
