摘要:	本研究計畫目標在開發高溫質子交換膜燃料電池堆(HT-PMEFC)之核心部件及高溫廢熱回收製冷之技術，並與業界廠商合作藉由整合本計畫團隊的關鍵技術，打造出一個移動式的甲醇重組製氫的發電系統。本計畫之研發重點包含HT-PEMFC之金屬電堆設計、膜電極組性能提升、新型觸媒材料開發、熱回收製冷技術及新型重組器研製，以開發一300 W的可攜式發電模組裝置，重量小於10 kg，體積小於10 L。可應用在露營或偏遠地區長時間連續且穩定供電，如救援供電、遠端環境監控與通訊基地台等，提升燃料電池應用價值。為進一步提升能源使用效率，將HT-PEMFC運作所產之廢熱源(約180 °C)回收利用，開發小型史特靈熱致冷機技術，整合冷、熱與發電(Combined cold and heat and power, CCHP) ，提升每單位甲醇之能源使用效率，發揮燃料電池的分散式儲能與發電特性。各預期工作指標為1)開發300 W金屬HT-PEMFC單電池與電堆技術及性能測試分析，使用商用膜電極，達到電流密度400 mA cm⁻² @0.6 V；2)進行HT-PEMFC膜電極性能提升及耐久性評估技術開發，完成1000 小時長時間測試與建立耐久性預估模型；3)開發高效且穩定之碳支撐 Pt/氧化物觸媒放大生產製程，並以電化學及微觀結構分析100 小時觸媒耐久性；4)研製液柱式史特靈熱致冷機以廢熱回收製冷功率200 W，性能指數0.5以上；5)開發一產氫量6 LPM微型甲醇製氫裝置。 ;The project team aims to develop the core components of high temperature proton exchange membrane fuel cell stack (HT-PEMFC) and a heat-driven cooling technology using the high temperature waste heat with a goal to produce a portable power generator with methanol reforming technology by linking the individual strength of the team members with an industrial manufacturer. The major goals include developing a HT-PEMFC stack using metallic gas distribution plates, enhancing the performance of membrane electrode assembly (MEA), exploring for novel catalyst materials, developing a heat-driven cooling technology and micro reformer to generate hydrogen from methanol for the portable fuel cell power unit, which aims to weigh less than 10 kg and smaller than 10 L. The device thus offers high value and can be applied in a remote location to provide stable and long lasting power for emergency power, remote environment monitoring and telecommunication, etc. To increase the energy efficiency, the project also aims to recycle the by-product heat (180 °C), using a small Stirling heat-driven cooler technology with a combined cold, heat and power, CCHP. Therefore, the strength of fuel cell as a distributed power can be leveraged.The anticipated targets of the project include: 1) completing the assembly of a 300 W metallic HT-PEMFC stack and its cell performance characterization, 2) developing characterization techniques for assessing the durability and reliability of the HT-PEMFC MEA and to finish a 1000 hour run-test of the in-house developed MEA, 3) developing high efficiency and stable carbon-supported Pt/oxides novel catalysts and the scale-up production process, and to analyze its reliability after 100 hours of use by characterizing the electrochemical and microstructure parameters, 4) designing and prototyping a liquid piston type Stirling heat-driven cooler that can give 200 W of cooling capacity with coefficient of performance 0.5, and 5) developing a micro methanol steam reforming hydrogen generator with hydrogen gas production rate 6 LPM for the HT-PEMFC system.
