    摘要:日前,清華大學的研究團隊攻克了氫燃料電池催化劑的產業化難題,而價格僅為同類進口產品的一半。

    氫燃料電池因為“高效率、零污染”的優點,越來越多應用于新能源汽車。但能讓氫燃料電池提供電能的關鍵材料——催化劑,我國一直依賴高成本的進口。日前,清華大學的研究團隊攻克了氫燃料電池催化劑的產業化難題,而價格僅為同類進口產品的一半。

    正在行駛的這輛公交車,就是我國第一臺采用全國產材料燃料電池驅動的公交車,它在湖北咸寧成功試運行。與傳統汽車相比,它的能量轉化效率高達50%至80%,是內燃機的2至3倍。氫燃料電池在西方發達國家的應用正在提速,因為它和純電動汽車相比具有明顯優勢。

    氫燃料電池的核心材料——催化劑,此前長期依賴進口導致高成本,制約了我國氫能產業的自主發展。2015年,清華大學通過校企合作聯合研發氫燃料電池技術。歷時兩年多,終于攻克了燃料電池催化劑量產技術,以及膜電極、雙極板等關鍵部件的技術升級和批量制備,實現了氫燃料電池關鍵材料及零部件的國產化,其成本比進口同類產品降低了50%至80%,部分零部件的性能指標已經超過進口產品。

    目前,催化劑系列化產品已應用在中科院、高校和多家燃料電池公司的燃料電池電堆中。已建成燃料電池催化劑量產線,產能達到1200g/天規模, 可滿足60臺燃料電池客車使用,并具備大規模工業化生產條件,預計今年我國燃料電池電堆的生產能力將達40萬千瓦。
