| 英文摘要 | carbon-coated titanium dioxide (tio2-c) has received much attention as a catalyst support in proton exchange membrane fuel cells. in this study, tio2 nanorod arrays (nrs) are hydrothermally grown on carbon paper and converted into tio2-c nrs by heat treatment at 900 degrees c under methane atmosphere. then, platinum nanoparticles are sputtered onto the tio2 nrs by physical vapor deposition to produce pt -tio2-c. the as-prepared pt-tio2-c exhibits high stability during accelerated durability tests. as compared with the commercial gas diffusion electrode (gde, 34.4% decrease), a minor reduction in the electrochemically active surface area of the pt-tio2-c electrode after 1500 cycles (10.6% decrease) is observed. when the as-prepared electrode with ultra-low platinum content (pt loading: 28.67 mu g cm(-2)) is employed as the cathode of a single cell, the electrode generates power that is 4.84 x that of the commercial gde (pt loading: 400 mu g cm(-2)). an electrode that generates power of 11.9 kw g(pt)(-1) (as the cathode) is proposed. the fabricated pt-tio2-c electrode can be used in proton exchange membrane fuel cells.
