Electrode with a Carbon Nanotube Array for a Proton Exchange Membrane Fuel Cell

One of the most important problems in development proton exchange membrane fuel cells remains selection an efficient electrocatalyst support capable providing a low loading active metal with minimal changes electrochemical surface, electronic conductivity, and activity. In this work, carbon nanotube arrays (CNTAs) grown directly on commercial gas diffusion layers (GDLs) are used to form electrodes new type. The CNTAs electrode as microporous layer. catalytic layer is formed by method that does not destroy structure consists controlled impregnation Pt-precursor subsequent reduction platinum particles surface volume resulting was studied scanning/transmission electron microscopy Raman spectroscopy. This provides increased electrical conductivity can also improve stability longer service life due enhanced adhesion materials GDL.
