直接甲醇燃料電池(Direct Methanol Fuel Cell, DMFC)是以甲醇做為燃料，將甲醇之化學能轉換成電能，相較於以氫氣作為燃料的質子交換膜燃料電池 (Proton Exchange Membrane Fuel Cell, PEMFC)，DMFC的甲醇燃料擁有相對高的體積能量密度，並且在常溫常壓下為液體，容易保存與攜帶，非常適合應用於個人攜帶式裝置的電源供應。
本研究主要發展應用於個人行動裝置的微型可撓曲直接甲醇燃料電池，並且針對其封裝技術進行改善，首先採用聚二甲基矽氧烷(Polydimethylsiloxane, PDMS)作為DMFC的主要結構使其擁有可撓曲之性質，利用PDMS翻模技術，製作出流道板，與製作完成的膜電極組組合後，再以PDMS包覆灌模的方式，將流道板以及膜電極組包覆在可撓曲的PDMS之內，以達到封裝及防漏的效果。
膜電極組製作的部分，陽極與陰極分別噴塗 1 mg 的Pt-Ru/C與Pt/C觸媒後，與質子交換膜(Nafion® 117)進行熱壓。在微型可撓曲直接甲醇燃料電池單電池測試中，陽極使用 1 M的甲醇做為燃料，陰極採用自然進氣，在平放的狀況下，最高發電功率可達6.64 mW，其開路電位為0.541V，在曲率半徑分別為2英吋與1英吋的情況下，最高發電功率分別為7.17 mW與8.05 mW，開路電位分別為0.536 V與0.551 V。
本研究也對電池做各種測試以及改善、研究刮刀製程並在碳布上添加微孔層應用於本研究的電池當中進行各項測試，以利未來將觸媒乘載量提高。本研究也嘗試將電池進行實際應用，在配合升壓模組後，串聯兩顆單電池可以成功的推動電子錶持續約4小時。

DMFC (Direct Methanol Fuel Cell) uses methanol as the fuel that converts the chemical energy of methanol into electrical energy. Compared with PEMFC (Proton Exchange Membrane Fuel Cell) using hydrogen as the fuel, methanol has relatively high volumetric energy density than hydrogen and is liquid at normal temperature and pressure. It is easy to store and carry. These unique properties make DMFC ideal for powering personal portable devices.
This research mainly develops the micro flexible DMFC used in personal mobile devices, and improves its packaging technology. Firstly, polydimethylsiloxane (PDMS) is used as the main structure of DMFC so that it has flexible nature. Secondly, use of PDMS molding technology to produce anode flow channel plate and then PDMS cladding filling mode, the flow channel plate and the MEA can be coated in the PDMS in order to achieve the effect of sealing.
MEA is fabricated by hot pressing the proton exchange membrane (Nafion® 117) by coding 1 mg of Pt-Ru/C and Pt/C catalyst separately on the anode and the cathode.
In the micro flexible DMFC test, the anode using 1 M of methanol as the fuel, the cathode with natural gas in the flat state, the maximum power up to 6.64 mW with an OCV of 0.541V and a maximum power yield of 7.17 mW and 8.05 mW at a radius of curvature of 2 inches and 1 inch respectively. The OCV were 0.536 V and 0.551 V, respectively.
