燃料電池因具有潔淨、高效率等特性，使得此新興能源科技的發展倍受重視。然而由於氫氣難以運輸及儲存之故，近年來由重組器提供富氫之混合氣體成為提供燃料電池燃料的解決方案之一。此種富氫氣體皆需經過純化處理，才能使一氧化碳濃度降低至燃料電池能夠承受的範圍，因此，為使燃料電池對於一氧化碳容忍程度能夠提升，並且簡化純化過程，開發重組式高溫型質子交換膜燃料電池成為未來趨勢之一。本研究以此型燃料電池做為研究主題，探討高溫型質子交換膜燃料電池於一氧化碳及溢入空氣條件下之特性研究。
本研究中，利用極化曲線、暫態電壓與電化學阻抗頻譜等方法進行燃料電池性能及阻抗之分析，探討參數包括電池溫度、氫氣濃度、一氧化碳濃度及溢入空氣之空氣濃度。實驗結果顯示，高溫型燃料電池對一氧化碳的容忍度隨著溫度上升而增加，在1%CO濃度、200 mA/cm2電流密度下，溫度由140增加至180oC時，電池性能增加29.33%，電池電壓輸出品質（SNR）增加14.12 dB；另外，降低氫氣濃度則會使一氧化碳對電池性能與阻抗之影響變得更顯著，在160oC、5% CO、電流密度200 mA/cm2時，H2濃度由40%提升到95%，SNR值上升14.6 dB。另一方面，溢入空氣，對於高溫型質子交換膜燃料電池性能改善較不明顯，在180oC、5% CO、電流密度為400 mA/cm2條件下，於陽極加入7.5% 空氣，電池平均電壓僅上升0.0234 V，但SNR值由9.96 dB增加到12.06 dB，說明溢入空氣能使電池輸出電壓品質提升。

The development of the new energy technology, fuel cells, draws attention because they have the characteristics of being clen and high efficiency. Due to the difficulties of hydrogen transportation and storage, it becomes a tendency to use reformers to supply the hydrogen-rich reformate for the fuel cell system in recent years. However, the reformate gas produced from a reformer has to be purified in order to reduce the carbon monoxide concentration to a range which is tolerable for a PEMFC. Thus, the development of reformate HT-PEMFC besomes one of the trend of the evolution of fuel cells to improve the carbon monoxide tolerance of the fuel cell and to simplify the gas purification process of the reformate fuel cell system. This study selects this type of fuel cell as the research topic to explore the characteristics of HT-PEMFC with CO and air-bleeding on the anode side.
In this study, the I-V curve, the long term constant current analysis and the electrochemical impedance spectroscopy are used to analyze the performance and the impedance of a HT-PEMFC. The control parameters include the operating temperature, CO, H2 and bleed air concentrations. The experimental results show that increasing the operating temperature increases the CO tolerance of the HT-PEMFC. The fuel cell performance is increased by 29.33% and the fuel cell voltage output quality, signal to noise ratio (SNR), is increased by 14.12 dB as the temperature increases from 140 to 180oC at 1% CO concentration and 200 mA/cm2 current density. In addition, effects of CO concentration on the cell performance and impedance become more significant as decreasing the hydrogen concentration. The SNR is increased by 14.6 dB as the H2 concentration increased from 40% to 95% at 160oC cell temperature, 5% CO concentration, 200 mA/cm2 current density. Moreover, the effect of air-bleeding on the improvement the HT-PEMFC under CO poisoning is not significant. The average voltage is only increased by 0.0234 V, but the SNR increased from 9.96 dB to 12.06 dB at the conditions of 180oC cell temperature, 5% CO concentration, 400 mA/cm2 current density and 7.5% air-bleeding. This indicates that the air-bleeding improves the output voltage quality of the fuel cell.
