臺灣博碩士論文加值系統

本文的宗旨在於建立一個迅速儲氫的系統，並且以無污染動力的概念，以太陽能供電給電解器產氫，再將所產的氫氣純化後儲存起來成為氫能。
而要達成此一目的，除了本實驗室既有的太陽能板以及氫氣產生器外，還必須改善氫氣產生器產氫之排放壓力過小的問題，為了避免氫氣儲存過於漫長而影響整個系統，因此有必要將低壓氫氣加壓至高壓以便排入儲氫合金罐，而這又牽涉到了必須設計一個加壓器來壓縮氫氣，因此加壓氫氣便成為此系統是否能順利運轉的關鍵。本文將探討如何設計出一適合的加壓器，討論如何將電解器出口低壓的氫氣壓縮成高壓，其整體過程將有理論模擬以及實驗的比較。除此之外，我們也使用一組八片的全新電池組，希望能改善產氫速率。
而完成了此一加壓系統後，發現確實可以將氫氣加壓至排放入儲氫合金罐內的理想壓力，因此氫氣儲存的問題可望解決。若能解決儲氫問題，不但能實現連續產氫的理想，還能使太陽能─氫氣產生器獨立發電系統完備，其系統在白天時收集太陽能供給蓄電池以及氫氣產生器，目的在於儘量於白天時將太陽能轉化為氫能，以便於晚上無陽光時利用氫氣供給燃料電池發電，以維持額定的負載。

Solar-hydrogen generator has a problem on storing hydrogen,the proposal of this paper is to establish a hydrogen storage system to improve the weakness of hydrogen generator.
Choosing metal hydride as a hydrogen storage,the idea storing hydroden pressuer is 8 atm,so compressing the hydrogen generated by hydrogen generator is necessary,then the hydrogen will be filled into metal hydride fast. Designing a compressing storage which can compress hydrogen to higher pressure.To improve the rate of hydrogen generating,we also adopt a new 8-stack cell electrolyser.
If the problem on storing hydrogen can be solved,the idea of “continuous generating hydrogen” would be achieved.It will also play a key role on ”Solar Hydrogen Fuel Cell and Battery Based Power System”. The system is equipped with a solar PV panel, a hydrogen fuel cell, an alkaline electrolyser, lead-acid batteries and hydrogen storage system. “Solar-Hydrogen system” is a emission-free operation. The fluctuation in available solar radiation necessitates energy storage to match the shifting of daily power demand.
