圓筒式氫氧產生器之研發與測試

本研究主要在製作一圓筒式氫氧產生器，並測試其產氣特性與效能。本系統以Stanley Meyer的共振電解理論為基礎，採用兩不同直徑之不銹鋼圓筒，以同心圓形式排列，浸入水中，分別接以電源之正負極，再施以純直流電及直流脈衝電流形式，驅使水分子在兩極間電場之作用下裂解，有別於一般電解水產氫之研究，本文目標是將氫氣作為燃燒用途，故不將氫氣與氧氣分離，而是產生氫氧混合氣。此具有當量混合比之混合氣簡稱氫氧或布朗氣體。本實驗紀錄於不同輸入電源形式下之耗水量與電流變化，再加以計算電流密度及其產氣量，並估計其法拉第效率及能量轉換效率。使用脈衝訊號輸入時，改變不同的脈衝頻率，並試圖找出金屬筒自然頻率對於其性能的影響。實驗結果顯示其能源轉換效率及法拉第效率會隨電源電壓之降低而增加，然而其電流密度與產氫量反而隨之降低。此外當脈衝頻率為30和35 Hz時，其能源轉換效率及產氫量皆有較好的表現，而此氫氧產生器的自然頻率也落在此頻率範圍，因此值得進一步探討此自然頻率與系統效能之關係。

In this study, a cylinder-type oxyhydrogen generator is presented and tested for its characteristic and performance of producing gases, based on a theory of resonated electrolysis proposed by Stanley Meyer. Two stainless tubes with different diameters are placed concentrically and imerged with pure water. The inner and outer tubes are connected to an electrical power source and served as positive and negative electrode respectively. Pure direct current and pulsed direct current are applied to split the water molecular under the electric field between two opposite electrodes. Contrary to the common research of water electrolysis, this study is intended to produce mixed rather than spererated hydrogen and oxygen gas for combustion purpose. This mixed hydrogen and oxygen gas is a mixture with stoichiometric ratio and called oxyhydrogen or Brown’s gas. The experiments are carried out by measuring water consumption and current variation under different type of electrical power input. The results are used to calculate the corresponding current density and gas production rate, and further evaluate the Faraday’s Efficiency and energy efficiency. Moreover, the effect of natural frequency of the stainless tube on the performance is investigated by varying the frequency of input pulse. The experimental results show that, as the input voltage decreases, the resulting energy and Faraday’s efficiency increase, while the current density and gas production rate decrease. Furthermore, for pulse frequencies of 30 Hz and 35 Hz, the resulting energy efficiency and gas production rate are significantly improved. Meanwhile; the natural frequency of the generator lies well within this frequency range. Hence, it is worthwhile to further examine the influence of this natural frequency on the system performance.
