Abstract
Low loading platinum-cobalt (Pt-Co) cathode catalyst on a Nafion(Na +)-bonded carbon layer is fabricated by using galvanostatic pulse technique to show the advantage of electrodeposition for high utilization of catalyst in proton exchange membrane fuel cell (PEMFC). We observed that Pt-Co catalysts evenly exist on the surface of carbon electrode and its thickness is about 5.8 μm, which is four times thinner than conventional Pt/C. Improved single cell power performance of Pt-Co cathode catalysts with a ratio of 3.2:1 compared with Pt/C is clearly presented. © 2011 Elsevier Ltd. All rights reserved.
