"本計畫延續前期貯氫合金反應容器之研究，擬達成以下數項目標：(1)研製高儲氫量新型貯氫合金，(2)設計並研製實用型反應容器，(3)反應容器吸放氫性能測試與模擬，(4)反應容器與1kW燃料電池整合性能測試，(5)依照上述結果提出氫燃料電池耦合微渦輪機複合氫電系統設計規劃。在貯氫合金製備方面，本計畫同時採用熔煉製程或機械冶金製程；熔煉製程包含小型真空或氣氛控制熔煉爐。新型儲氫合金包含若干重量輕而吸氫量高的三元或多元系統合金，如摻雜鐵、鈀或奈米碳材的鎂鎳基合金，Na-Al基或Li-Al基等。此等合金將製備成鑄細條狀，經搗碎成細粒後，再填入儲氫容器內供儲氫運作。至於實用型貯氫反應容器之研製，參考前期計畫之研究成果，整合成「氫燃料電池耦合微渦輪機發電之複合氫電系統」作為最終研究目標。本期計畫擬先完成研製一約5kg鎂基貯氫合金且能耐高溫及高壓之千瓦級反應容器，輔以精確之邊界控溫及內部控溫。反應容器所需之熱源，擬利用模擬微渦輪機發電所排放廢熱，以提昇整體發電系統效率。第一階段先進行反應容器研製與吸放氫測試與數值模擬；第二階段再將反應容器與1kW燃料電池進行整合與測試；最後階段綜合貯氫反應容器性能測試與評估結果，儲氫反應容器與燃料電池整合運作經驗，提出「氫燃料電池耦合微渦輪機發電」之設計方案，以供作後續研製「複合氫電系統」之基礎。" "This project serves as continuation of the former research project which dealt with testing on hydrogen absorption and desorption of a small storage tank. A number of goals are to be accomplished in the present project. These are: (a) preparation and testing on properties of high-weight-percent new hydrogen storage alloys, (b) design and fabrication of a mid-size metal hydride (MH) reaction tank, for practical usage, (c) simulation and testing on hydrogen absorption and desorption of the tank, (d) testing on a combined system which consists of the hydrogen storage tank and a 1kW fuel cell, and (e) a hybrid hydrogen power system including a hydrogen fuel cell and a micro-turbine, to be proposed based on the results extracted from above-mentioned works. In the aspect of hydrogen storage alloy manufacture, both the high temperature melting process and powder mechanical alloying process will be applied in this project. A new type of several ternary or quaternary systems of hydrogen storage alloys will be developed. These alloys essentially are light weight with high content of reversible hydrogen absorption, such as Mg-Ni based alloy with addition of Fe, Pd or/and nano carbon tube (NCT), Na-Al based alloy and Li-Al base alloy. The cast strips of alloy will be pounded to small pieces, and then filled into the vessel for hydrogen storage application. According to the results of the former project, a mid-size MH tank will be designed and fabricated. The results extracted from the present project and the former one will be integrated to achieve the ultimate goal: to develop a hybrid hydrogen power system, which is mainly a hydrogen fuel cell and a micro-turbine coupled system. In the present project, about 5 kg Mg-based alloy is to fill in the MH tank, being able to sustain high temperature and pressure. The temperature of both the wall and the inner space of the tank is precisely controlled. In the hybrid hydrogen power system, to improve the overall efficiency, the exhausted gas from the micro-turbine is used to heat the MH tank for hydrogen release. To simulate this process, a gas heat exchange system is designed for supplying and extracting heat from the MH tank. At the first stage of the current project, the reaction tank will be fabricated, tested and numerically simulated for hydrogen charge and discharge. At the second stage, the MH tank will be integrated with a 1-kW fuel cell for testing. At the last stage, the hydrogen fuel cell and micro-turbine coupled system will be proposed. The layout described in the proposal can be utilized for developing the hybrid hydrogen power system."
