An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange. It is an insoluble matrix (or support structure) normally in the form of small (0.25–1.43 mm radius) microbeads , usually white or yellowish, fabricated from an organic polymer substrate.
質子交換膜 （proton exchange membrane），或稱 高分子電解質膜 （polymer electrolyte membrane；二者均簡稱 PEM ），是一種 離子聚合物 的 半透膜 ，設計用於 質子 傳導隔絕 氧 或 氫 [1] 。 主要應用於 質子交換膜燃料電池 的 膜電極組 （MEA），分離反應物及傳導質子。 PEM材質可由純 聚合物 膜或 複合 膜製作。 最常見的和市售的質子交換膜的材料是 全氟磺酸 的 含氟聚合物 （PFSA）， 杜邦 產品 [2] [3] 。 Nafion是與像聚四氟乙烯全氟化主鏈的離聚物，有用於製造質子交換膜的 離聚物 許多其他的結構基序 [4] 。 許多使用 多環芳烴 聚合物而其他人使用部分 氟化聚合物 。
