Paper Title:
Hydrogen Evolution Properties of Carbon Supported PtCu-LaOX Composite Multi-Layer Membrane Electrode Materials
  Abstract

In order to reduce production cost of making H2, one of the key points was to reduce Pt loading in Pt/C catalytic electrode. In our study, a new type of Pt/C membrane electrodes -- PtCu/C (abbr. P), PtCuLaOx/C (abbr. PL), PtCu-LaOx/C (abbr. P-L), LaOx-PtCu/C (abbr. L-P), LaOx-PtCu-LaOx/C (abbr. L-P-L) and PtCu-LaOx-PtCu/C (abbr. P-L-P) composite multi-layer membrane electrodes -- would be raised, in which with developing different membranouslayer form and different La content homogeneously dispersed on the surface of carbonaceous substrates was manufactured by Ion Beam Sputtering (IBS) technology. The hydrogen evolution polarization curves of these electrodes were tested by tri-electrode system, and were calculated results of their exchange current density (i0) and decomposition voltage (Ed). It was found that PtCu-LaOx composite multi-layer membrane with Pt loading less than 0.05mg/cm2 (the electrode area) whose Ed and i0 was -0.227(V vs SCE) and 4.717mA/cm2 respectively in balanced condition.
