質子交換膜燃料電池之系統製作與模擬

Abstract

本研究將針對質子交換膜燃料電池（Proton Exchange Membrane Fuel Cell, PEMFC）之輕質化電池組進行設計。由於雙極板佔燃料電池組百分之九十的體積，為主要重量來源，因此新型複合雙極板將選用輕質材料披覆導電銅層與金層，使得非鐵金屬或非金屬材料具有金屬化結構，以達到具有電傳導特性及較佳物理、化學等特性。本研究所製作之電池組，可較傳統電池組減低70%之重量。 本研究第二部份是使用美商國家儀器公司所開發之軟體─LabView，利用程式控制之方式，擷取實驗所開發質子交換膜燃料電池電池組之性能。此外建構混合電力系統應用於生態養殖之範例，藉由程式控制與資料擷取，根據生態養殖系統所需之電力負荷，取得太陽能電池與備用電源之發電功率，透過備用電源之模擬，取得所需燃料電池之系統。未來將可針對各種需求的電力負荷，藉由相似性分析的方式，將燃料電池及太陽能電池之電力系統擴大化。

This study provided a lightweight design in proton exchange membrane fuel cell. because the bipolar plate occupy the ninety percent of the volume, and the main source of weight in PEMFC, so this study decreased the weight and cost by choosing plastic material which is coated with conductive copper and gold to be bipolar plate. Making the non-ferrous metal or non-metallic materials have metal structures like electrical conductivity, the physical or chemical and other properties. The stack’s weight in this study can be decreased 70% than conservative stack. The second part of this study is using LabView which developed by National Instruments Corporation, to get the performance data from proton exchange membrane fuel cell stack and each cells in this stack. And provide an example of ecological farming to be the hybrid power system application, through program control and data acquisition, to get the power data of ecological farming system load requirement. According the solar cell and backup power’s performance to simulate fuel cell’s specifications. This application will be amplify to base on the demand for the variety of electrical load in the Future.
