摘要
質子交換膜燃料電池(PEMFC)具有高功率密度、啟動快、操作溫度低等特點,因此應用領域十分廣泛,目前較常見的是低溫型 PEMFC,其操作溫度≤80oC,因此遭遇了許多困難如一氧化碳耐受 度低、散熱問題等,而這些問題在高溫型PEMFC將可獲得改善,操作溫度約為120-200oC,但高溫致使組件材料面臨極大的挑戰,本文將介紹高溫型質子交換膜燃料電池的優、缺點,並說明當操作 溫度提升時,各關鍵組件將面臨什麼樣的問題,並特別針對雙極板組件建置一套高溫化學穩定驗證技術,用以評估板材之適用性。

Proton electrolyte membrane fuel cell (PEMFC) is thought to be one of the most promising candidate of new energy. It has the advantages of clean, high power density, short start-up time and operating in low temperature. Current PEMFC which is operating at low temperature (≤ 80oC), suffers from several problems like CO tolerance, heat and water managements. These problems can be solved by increasing the operating temperature to 120-200oC, which is called high-temperature PEMFC(HT-PEMFC). However, the cell components meet much more challenges at higher temperature. This paper overviews the advantages and disadvantages of HT-PEMFC and the challenges of component materials, and provides a test method for evaluating the chemical stability of bipolar plates at high temperature.
