本研究著眼開發一創新觸媒燃燒室應用於熱光電(thermophotovoltaic,TPV)系統上，以克服小型燃燒室常面臨如：滯留時間(residence time)不足、熱散失(heat loss)、壁面冷熄(wall quenching)等問題，，且由文獻中指出白金觸媒在高溫下輻射光譜會往短波長移動之特性，容易與光電板之吸收波段相符，故將白金選做熱光電燃燒室輻射(emitter)材料，並藉由白金觸媒效應增加小型燃燒室之操作區間，配合新式火焰穩駐設計，改善熱散失，達到貧油燃燒熱光電系統之目的。
從燃燒現象探討，與傳統背向階梯(backward facing step)設計相比，觀察燃料供給速度和當量比分別對兩者造成了不同影響，使用熱電偶和紅外線熱像儀等器材，透過亮度、溫度與穩駐位置等討論，得出適宜的操作區間。並將燃燒器輻射器與銻化鎵(GaSb)光電板整合成一熱光電系統，測試幅射光譜與光電板輸出效能等，評估整體系統之理想化效益與實際差異，進而尋找可行的改善方式。測試結果發現觸媒對於小型燃燒室之助益，與新式環繞孔洞設計配合內外燃料供給加熱，具有穩駐火焰、增加可燃區間、減少熱散失等優點。可明顯達到貧油觸媒燃燒與感善熱光電效率的目的。

The research is focused on a novel combustor to be used on meso-scale thermophotovoltaic (TPV) devices. In order to overcome problems often encountered in miniature power systems, such as short residence time, heat loss and wall quenching, we propose a novel setup of using platinum as the catalyst as well as the emitter for TPV. It has been pointed out in other research that platinum can emit shorter wavelength at higher temperature than usual, which can be used as the material of an emitter. Moreover, using platinum catalyst can increase combustion temperature by 200°C and theoretically significantly enhance the emission efficiency.
The current combustor design consists of a percolated Pt catalyst tube in the TPV combustor to stabilize the flame, enhance combustion and emit high temperature radiation. We used an R type thermocouple and a thermal vedio system (TVS) to measure the tube exit and wall temperature, so that we can identify the flame anchor position and distinguish the brightness. Compared with the backward facing step desigh of a traditional TPV combustor, the proposed percolated hole desigh is proved to have a wider operating range. The proposed combustor is also integrated with the GaSb PV cell, then measure the spectrum and I-V curve. The advantage of the outstanding features of the proposed catalyst TPV combustor is partially verified in the current research and further research in the future is urged.
