在核聚变装置中，必须将真空废气中的氢同位素及其化合物与其他气体分离，并作为氢同位素气体回收，用于氚的再循环。我们提出了利用质子传导陶瓷进行氢回收。通过向包括质子导电陶瓷作为电解质的电化学电池发送直流电，氢在高温下选择性地从阳极室泵送到阴极。氢在阳极电离产生质子，质子在阴极通过以下反应被传输和去电离形成氢：H2 ！2Hþ þ 2e（阳极）ð1Þ 2Hþ þ 2e ！H2（阴极）：ð2Þ
In a nuclear fusion device, hydrogen isotopes and their compounds in the vacuum exhaust gas must be separated from other gaseous species and recovered as hydrogen isotope gases for tritium recycling. We have proposed the use of proton-conducting ceramics for the hydrogen recovery. By sending a direct current to an electrochemical cell including the proton-conducting ceramic as an electrolyte, hydrogen is pumped selectively from the anode compartment to the cathode at high temperature. Hydrogen is ionized at the anode to produce protons, which are transported and deionized to form hydrogen at the cathode by the following reactions: H2 ! 2Hþ þ 2e (at anode) ð1Þ 2Hþ þ 2e ! H2(at cathode): ð2Þ
