隨著高科技產業的發展,對於微衛星及微飛機等小型飛行載具的需求及其功能的要求也相對的提高,因此研發微小的能量供應器已是刻不容緩的工作。而觸媒燃燒反應以高活性的觸媒表面,提供燃氣在低溫及低當量比的狀態下氧化、釋熱,由於其降低反應活化能的特性,使其成為近年來倍受各界矚目且一致認為最有潛力的燃燒技術。
本研究以氫氣與氧氣在白金觸媒平板上的放熱反應作為能量的來源,配合微機電技術將白金薄膜電阻製作於基材為玻璃的晶片上,以此為反應所需的觸媒及溫度量測元件,並與蝕刻出微流道的上蓋板結合成微反應系統,便可利用感測器得知反應系統管道內溫度變化的劇烈程度。
利用流量來控制微管道內反應氣體的流速以進行實驗,當晶片預熱溫度為400℃時,燃氣於管道入口附近即產生釋熱反應,並隨著流速增加,反應溫度亦隨之上升,最高溫可達498℃。本文對實驗所得數據進行分析但所得推論仍需更多的實驗來加以證明與探討。
Due to booming development of MEMS technology, it is clamant to develop mini-scale power supply systems because the requirement of powerful micro-satellite and micro air vehicle are increasing. As we know, the catalysis from the active surface makes the chemical reaction alive in low temperature and lean fuel conditions. Therefore, the micro catalyst reaction is recognized by more and more people to be the most potential micro-scale combustion technology.
In this thesis, the catalysis from reaction of hydrogen and oxygen on Pt film is the power source of micro reactors, which designed and fabricated by MEMS technology. The Pt thin film resistors, which fabricated on glass substrate, are used to be the catalyst and temperature sensors. After bonding this chip with the glass base channel etched by BOE, the reactor is already to making tests.
The velocity of reaction gas in channel is controlled by gas flow rate. When the preheat temperature of reaction chip is 400℃,the reaction is displacement near the inlet of channel. The reaction temperature is increasing with increase of flow velocity, and the highest temperature of the reactor is 498℃.However the conclusion in this thesis must have more experiments and disputations to prove the suppositions.
