摘要
本篇論文主要用PIC18F452 Microcontroller 發展並且實現1KW 質子交換膜燃料電池(PEMFC)控制模組。我們使用PIC18F452 Microcontroller去發展一片新的控制電路板取代巴拉德(Ballard)產品原有的控制電路板。實驗結果顯示在巴拉德產品的固定負荷下相同產量效率比較幾乎是一樣的。 我們的論文裡包含了4個控制電路。它們是自我測試的電路、氫氣、氧氣和溫度控制電路。我們的系統的特徵如下。第一，4片控制電路的操作由微處理器PIC18F452來進行控制。其次，使用安全控制電路來偵測這塊電路板裡的組成部分功能。第三，氫氣和氧氣的輸出入量分別被氫和氧的控制電路調整。第四，電池的溫度以溫度控制電路監視著以提供適當數量的氫和氧。 我們的主要貢獻如下︰ 1. 我們提議的控制模組更便宜和簡單。 2. 本論文提議之控制方式可利用於其他燃料電池系統做更進一步的應用。

This thesis mainly addresses on development and implementation on the 1KW PEMFC control module with the PIC18F452 microcontroller. We submitted a new control circuit board with the PIC18F452 microcontroller to substitute the original controller in Ballard Product. The experimental results show that the output efficiency is almost the same as Ballard Product under fixed load. Four control circuits are included in our proposal. They are Self-test Circuit, Hydrogen Circuit, Oxygen Circuit and Temperature Control Circuit. The features of our system are as follows. First of all, the operation of the four control circuits is handled by the Microprocessor PIC18F452. Secondly, the safety control circuit is used to detect the components contained in the circuit board to maintain its functions. Thirdly, the amount of hydrogen and oxygen is adjusted by the control circuits of hydrogen and oxygen, respectively. Finally, the cell temperature is monitor by the temperature monitor circuit to supply the proper amount of hydrogen and oxygen. Our main contributions are as follows： 1. Our proposed control module is cheaper and more simples. 2. The proposed scheme can be augmented to further applications of other fuel cell system.
