介绍了膜类型和电解质组成对使用Ag气体扩散电极电化学生成合成气（CO + H2）的影响。从阳离子交换膜变更为阴离子交换膜（AEM）延长了低Ecell值（高达4倍）下的电解槽操作时间，而不影响产品组成。使用KOH作为阴极电解液降低了E电池，并导致电解液成本降低39%。在低Ecell值下确定操作时间的主要因素是维持足够高的阳极电解液pH的能力。
The impact of membrane type and electrolyte composition for the electrochemical generation of synthesis gas (CO + H2) using a Ag gas diffusion electrode are presented. Changing from a cation exchange membrane to an anion exchange membrane (AEM) extended the cell operational time at low Ecell values (up to 4x) without impacting product composition. The use of KOH as the catholyte decreased the Ecell and resulted in a minimum electrolyte cost reduction of 39%. The prime factor in determining operational time at low Ecell values was the ability to maintain a sufficiently high anolyte pH.
