    Abstract: 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。
    The main objective of this paper is to apply the polydimethylsiloxane(PDMS) on a disc type direct methanol fuel cell(DMFC).There are two parts of this paper, the first part is to adopt the PDMS on a substitute material of the gasket and flow board. The performance of the DMFC with PDMS materials are compared with the DMFC which contains Teflon(PTFE) gaskets and acrylic flow boards. The effect of the surface treatment on the anode and cathode flow boards is also studied.
    The second part of this paper is to apply the PDMS materials on the design and fabrication of the disc type DMFC .The current collectors are bounded with a circular PDMS thin film before the DMFC assembly. Then the anode and cathode flow boards and the PDMS thin film with current collectors are assembled together. A single layer disc type DMFC with 3 MEAs is designed and fabricated first. The performances of the individual cell and overall DMFC module are measured. The effect of the screw torque is also discussed. Furthermore, a double-layer disc type DMFC with 3 MEAs at each layer is designed and fabricated. The performances of individual cell as well as overall DMFC module are also measured. At the end of this thesis, the developed double–layers DMFC is combined with one liquid pump, one air pump, and a DC-DC converter to accomplish as a small portable charger.
