先進船舶電力－－質子交換膜燃料電池設計製備與性能分析之研究

Advanced Ships Electric Power-Study on the Design Practice and Performance Analysis of the Proton Exchange Membrane Fuel Cell

本文主要探討燃料電池在船舶電力上之應用，以及針對質子交換膜燃料電池（PEMFC, Proton Exchange Membrane Fuel Cell）進行實驗研究，並建立其設計、製備與性能分析之能量。以燃料電池測試台進行相關之性能測試時，實驗控制參數包括電池溫度、相對飽和溫度、背壓以及燃料（H2、O2）質量流率等。實驗結果經與現行文獻資料比對，在各組不同之參數條件下，相關性能曲線均相當吻合。實驗研究亦發現，在H2及O2的消耗量上可得到最佳比例，且控制燃料電池溫度及加濕氣體溫度與增加進氣（H2、O2）的背壓均具有提昇電池性能的效果。本研究除完整地建立質子交換膜燃料電池設計、製備、性能測試與分析能量外，其結果亦有助於國內先進船舶電力設計之發展。 The application of proton exchange membrane fuel cell (PEMFC) on ship electric power is first discussed in this paper, and then the design work and performance analysis of PEMFC is also investigated experimentally. During tests are executed, the considered operating parameters include cell temperature, relative saturation temperature, back pressure, and the fuel (H2, O2) flow rates. Comparing current results with previous literature for different cases, the performance curves are matched well. According to the result of the experiments, the consumptions of H2 and O2 are agreed with the ideal ratio. Meanwhile, to change the temperature of fuel cell and the humidification, and to increase the back pressure of inlet flow is helpful to improve the cell performance. The above study not only completely establishes the design, testing, and analysis capacity for PEMFC, but also benefits to the development of advanced electric power design on ship in domestic.
