Manufacture of Carbon Supported PtCuLaOX Membrane Electrode with Low Pt Loading by IBS Technology
For the use of Fuel Cells in transportation, one of the key points is to reduce Pt loading in Pt/C catalytic electrode. In our study, a new type of Pt/C membrane electrodes, PtCuLaOx heterogeneous structure, in which with developing different La content homogeneously dispersed on the surface of carbonaceous substrates was manufactured by Ion Beam Sputtering (IBS) technology, and also was treated by different annealing temperature in muffle furnace. It was found that PtCuLaOx heterogeneous membrane with Pt loading less than 0.05mg/cm2 (the electrode area) in which its having complicated valence state, indicated that Pt had mutual effect with Cu, La and O, respectively. In addition, along with increases the annealing temperature, the instant result was to promote alloying of Pt, Cu and La in PtCuLaOx/C catalytic electrodes.
