Abstract Adding metal phase as the electronic transport channels in mixed protonic and electronic conductors is an effective method to enhance the conductivity and hydrogen permeability. Ceramic-metal (cermet) Ni-BaCe0.85Fe0.15O3-δ (Ni-BCF8515) dual-phase membranes were successfully fabricated in this article, where BaCe0.85Fe0.15O3-δ (BCF8515) served as the protonic conductor and Ni acted as the electronic conductor. The hydrogen permeability of Ni-BCF8515 dual-phase membrane was improved apparently, reaching 0.325 mL min−1 cm−2 at 1000 °C, which is four times higher than that of the single phase BCF8515 membrane. Hydrogen permeability of Ni-BCF8515 dual-phase membrane under different hydration conditions was studied here. Moreover, Ni-BCF8515 dual-phase membrane showed stable hydrogen permeability under the reducing atmosphere for 50 h.

Ni-BaCe0.85Fe0.15O3-δ金属陶瓷膜的氢分离性能评价

摘要 在混合质子和电子导体中添加金属相作为电子传输通道是提高电导率和氢渗透率的有效方法。本文成功制备了陶瓷-金属（cermet）Ni-BaCe0.85Fe0.15O3-δ（Ni-BCF8515）双相膜，其中BaCe0.85Fe0.15O3-δ（BCF8515）作为质子导体，Ni充当作为电子导体。Ni-BCF8515双相膜的氢渗透率明显提高，在1000℃下达到0.325 mL min-1 cm-2，是单相BCF8515膜的四倍。这里研究了 Ni-BCF8515 双相膜在不同水化条件下的氢渗透性。此外，Ni-BCF8515 双相膜在还原气氛下 50 小时显示出稳定的氢渗透性。
