在基于SrCe(0.95)Yb(0.05)O(3-α)质子导体电池的电化学氢泵中，研究了供应到阴极的水蒸气和操作温度对泵送特性的影响。通过增加对阴极的水蒸气供应以及在700-900摄氏度的检查范围内降低操作温度，可以增强抽氢能力。阴极处存在足够的水蒸气将保持氢泵的电流效率。 (C) 2001 Elsevier Science B.V. 保留所有权利。
In the electrochemical hydrogen pump based on SrCe(0.95)Yb(0.05)O(3-alpha) proton conductor cell, effects of water vapor supplied to the cathode and operation temperature on the pumping characteristics were examined. Hydrogen-pumping capacity could be enhanced by increasing water vapor supply to the cathode and by reducing operation temperature within the examined range of 700-900 degreesC. Presence of sufficient water vapor at the cathode would keep the current efficiency of the hydrogen pump. (C) 2001 Elsevier Science B.V. All rights reserved.
