Optimization of carbon-supported platinum cathode catalysts for DMFC operation. [PDF]

open access: yes, 2002
In this paper, we describe performance and optimization of carbon-supported cathode catalysts at low platinum loading. We find that at a loading below 0.6 mg cm-2 carbon-supported platinum outperforms platinum black as a DMFC cathode catalyst. A catalyst

Pdms applied on the design and fabrication of the disc type dmfc component

open access: yes, 2010
碩士本論文主要探討聚二甲基矽氧烷(PDMS)應用於圓盤式直接甲醇燃料電池(DMFC),論文分為兩部份;第一部份為利用PDMS取代原有的材質,並製成防水墊片及流道版,比較以PDMS為材質製成的DMFC,與以鐵氟龍防水墊片及壓克力流道板所製成的DMFC的效能,並探討表面處理對陽極及陰極流道板的影響。 本論文的第二部份為將PDMS應用於圓盤式DMFC的設計與製作,在組裝DMFC之前,先將集電片與圓型PDMS薄膜鍵合,接著將陽極與陰極流道板與具集電片之PDMS薄膜組合 ...
