首次在具有氧去极化阴极的燃料电池型反应器中进行HCl到氯气的气相电解。在4 kAmm（-2）的工业相关电流密度下，获得了低于-1 V的非常低的电池电压。与技术HCl电解工艺相比，这导致电能需求减少约30%。阴极入口气体的温度和相对湿度（rH）被确定为控制系统整体性能的关键参数。(C)2013爱思唯尔有限公司版权所有。
For the first time, gas-phase electrolysis of HCl to chlorine was conducted in a fuel cell type reactor with an oxygen depolarized cathode. Very low cell voltages below - 1 V at industrially relevant current densities of 4 kA m(-2) were obtained. Compared to technical HCl electrolysis processes, this leads to a reduction in electrical energy demand of approximately 30%. The temperature and the relative humidity (rH) of the cathode inlet gas were identified as key parameters controlling the overall performance of the system. (C) 2013 Elsevier B.V. All rights reserved.
