技術說明

質子交換膜燃料電堆在運轉時有控溫之問題，傳統水冷式散熱雖能有效散熱維持電 池性能，但卻需要額外的體積及重量。本產學計畫將與「新力能源科技股份有限公 司」共同開發內鑲式水冷流道燃料電池，將水冷流道內鑲於電池流道內，整合水冷 流道及氣體流道於雙極板中，藉由流道設計，使雙極板中除原本之氣體流道，再額 外內鑲水冷流道，省去傳統水冷板之加裝，期望降低質子交換膜燃料電堆之體積、 重量與生產成本。組裝一PEMFC之單電池並量測其性能曲線與長時間耐久性，並 進一步的優化此種雙極板，同時針對內鑲式水冷流道燃料電池之氣密與水密技術進 行開發。本產學計畫最終目的為降低燃料電池之體積與重量並維持電池性能，有效 提升其體積功率密度，提高「新力能源」燃料電池技術之市場競爭力。本計畫所開 發之｢內鑲水冷流道雙極板之質子交換膜燃料電池｣，比起傳統水冷板之水冷式散熱 設計，預期可減少約10%之電堆體積。 We need to control the temperature of a proton exchange membrane fuel cell stack when operating it. Traditional design uses separate water cooling plates between the cells. It is very efficient method to control stack temperature, but need extra volume and weight. This project collaborates with Eco-Energy Technology Co., Ltd. to develop new water-cooling design. We integrate watercooling channel and the gas flow channel into the bipolar plate to reduce the volume, weight, and cost of fuel cell stack. Single cells with built-in water cooling channels will be manufactured to measure the I-V curves and long-term durability. Then improve the water management, reduce the volume and maintain the performance of the fuel cells to increase volume power density. The goal of this project is to reduce the stack volume by at least 10% compared with the traditional water cooling design.
