由於燃燒化石燃料作為能量的來源,造成許多環境的問題,如空氣汙染、酸雨和溫室效應,已經嚴重地影響人類的生活。相對之下,氫燃料電池提供了非常乾淨的能量來源,因此已引起密切的關注。本研究提出設計和製造氫燃料電池的重要組成之一,即氫氣儲存/攜帶裝置。本裝置設計的理念,是以簡單的電訪製程,製造出更高氫氣儲存量,具重量輕且易於運輸及可重複使用之裝置。硼胺,當加熱後,會釋放出它的二十重量百分比的氫氣,被用來作為氫氣來源的材料,藉由同軸電氣紡絲,用聚碳酸酯封裝硼胺,以製造微米尺寸內/外管纖維排列薄膜。它們的型態藉由掃描式電子顯微鏡觀察,以X光繞射儀、熱示差掃描分析儀、傅立葉轉換紅外線光譜儀進行微細結構觀察,並估計硼胺的形成和含量。氫氣的釋出經由熱重分析儀和氣相層析法檢驗。最後它的機械性質藉由質地剖面分析儀測定。型態和光譜的結果證明,高達四十重量百分比之硼胺可被聚碳酸酯封裝,而這些包含硼胺的微米尺寸纖維具有獨特高度順向和緊密排列方式等特徵,便於日後製作成高密度模組。更重要的是,經由氣相層析法及熱分析證實,在本複合纖維陳列薄膜之組合下,更多的氫氣能被有效地釋出。綜合本實驗數據顯示,含有硼胺的微米尺寸內/外管纖維排列的潛在能源應用,具有重量輕及有效的氫氣的儲存/攜帶的優點,日後將可應用於氫氣燃料電池之氫源提供。

Many problematic environment events, such as, air pollution, acid rain and greenhouse effect, caused by the combustion of fossil fuels as source of energy, have seriously impact on human living. To the contrary, hydrogen fuel cell, presenting a very clean energy source, therefore, has drawn intensive attentions. This study presents design and fabrication of one of the important component of hydrogen fuel cell, namely, the hydrogen storage/carrier device. The potential advantages for fabricating this device by electrospinning process include larger hydrogen storage capacity, ease of handling/transportation, and reusability. Ammonia borane, (AB, NH3BH3), released up to 20 wt.% of its original weight of hydrogen as heated, was used as hydrogen-source material. By coaxial electrospinning, membranes of micro scale core/shell fibers array (CSFA) were fabricated with NH3BH3 encapsulated by polycarbonate (PC). Their morphology were characterized by scanning electronic microscopy (SEM), X-ray diffraction (WXD), differential scanning calorimetry (DSC) and Fourier Transfer Infrared spectroscopy (FTIR) were conducted to investigate microstructure, and it would provide a comparative estimation on the formation and content of AB. Release of H2 was followed via thermogravimetric analysis (TGA) and examined gas chromatography (GC). Finally, the mechanical properties were determined with a texture profile analyzer. Morphological and spectroscopic results showed that the encapsulation of AB (up to 40 wt.%) by PC shell was successful and these AB-containing CSFA’s kept the unique structure of highly aligned and closely connected, in favor of fabricating the high-density modulus in the future. The most important finding was the highly aligned composite fibrous membrane could release more hydrogen effectively, confirmed by GC and TGA. All these data suggest the potential applications of AB-containing CSFA as a light weight and effective hydrogen storage/carrier for hydrogen fuel cell.
