研究了质子交换膜 (PEM) 堆栈电解槽（9 个几何面积为 100 cm(2) 的电池）在不同温度下的电化学特性。在 60 A (600 mA cm(-2)) 和 70 摄氏度、876 W 施加的电功率下产生了与 2701h(-1) 类似的 H-2 量。该过程相应消耗的比能量为3.24 Wh.1(-1)H(2)。确定了法拉第效率和电效率。在 60A 和 70℃ 下，相对于氢气的低热值和高热值，总电堆效率分别为 73% 和 85%。这些结果证实了先前实验室规模设备的成功放大。版权所有 (C) 2011，Hydrogen Energy Publications, LLC。由爱思唯尔有限公司出版。保留所有权利。
The electrochemical properties of a proton exchange membrane (PEM) stack electrolyzer (9 cells of 100 cm(2) geometrical area) were investigated at different temperatures. An amount of H-2 of similar to 2701h(-1) was produced at 60 A (600 mA cm(-2)) and 70 degrees C under 876 W of applied electrical power. The corresponding specific energy consumed in the process was 3.24 Wh.1(-1)H(2). The Faradic and electrical efficiencies were determined. Overall stack efficiencies of 73% and 85%, at 60 A and 70 degrees C, with respect to the low and high heating value of hydrogen, respectively, were obtained. These results confirmed the successful scale-up of a previous lab-scale device. Copyright (C) 2011, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd. All rights reserved.
