鈀合金可制成膜片(稱鈀膜)。鈀膜的厚度通常為0.1mm左右。主要于氫氣與雜質(zhì)的分離。鈀膜純化氫的原理是，在300—500℃下，把待純化的氫通入鈀膜的一側(cè)時(shí)，氫被吸附在鈀膜壁上，由于鈀的4d電子層缺少兩個(gè)電子，它能與氫生成不穩(wěn)定的化學(xué)鍵(鈀與氫的這種反應(yīng)是可逆的)，在鈀的作用下，氫被電離為質(zhì)子其半徑為1.5×1015m，而鈀的晶格常數(shù)為3.88×10-10m(20℃時(shí))，故可通過鈀膜，在鈀的作用下質(zhì)子又與電子結(jié)合并重新形成氫分子，從鈀膜的另一側(cè)逸出。在鈀膜表面，未被離解的氣體是不能透過的，故可利用鈀膜獲得高純氫。雖然鈀對(duì)氫有獨(dú)特的透過性能，但純鈀的機(jī)械性能差，高溫時(shí)易氧化，再結(jié)晶溫度低，易使鈀管變形和脆化，故不能用純鈀作透過膜。在鈀中添加適量的IB族和Ⅷ族元素，制成鈀合金，可改善鈀的機(jī)械性能。
