微孔层是聚合物电解质膜燃料电池和水电解槽中气体扩散电极的重要组成部分。它在纳米结构化催化剂层和宏观结构化电极体之间形成界面。在PEM水电解的情况下，这种层迄今为止仅应用于阴极。另一方面，它通常不存在于电池的阳极侧。在本研究中，这样的层被集成到PEM水电解槽的阳极中。它是基于锑掺杂的氧化锡放置在钛毡形成电极背衬。使用内部合成的IrO 2，制造具有和不具有微孔层的气体扩散阳极，并在实验室PEM水电解器中比较它们的性能。记录了电流-电压曲线和电化学阻抗谱。结果表明，微孔层仅在低电流密度范围内具有优势，而在较高电流密度下，微孔层的欧姆电阻显著降低了电解效率。图形摘要
AbstractA microporous layer represents an important element of the gas diffusion electrodes used in polymer electrolyte membrane (PEM) fuel cells and water electrolysers. It forms an interface between the nanostructured catalyst layer and the macrostructured electrode body. In the case of PEM water electrolysis such a layer has only been applied to the cathode to date. On the other hand, it is typically absent on the anode side of the cell. In the present study, such a layer was integrated into the anode of a PEM water electrolyser. It was based on antimony-doped tin oxide placed on titanium felt forming the electrode backing. Using an in-house synthesised IrO2, gas diffusion anodes were manufactured with and without the microporous layer and their performance compared in a laboratory PEM water electrolyser. Current–voltage curves and electrochemical impedance spectra were recorded. The results revealed that the microporous layer is only advantageous in a range of low current densities, while at higher current densities the ohmic resistance of the microporous layer significantly reduces the efficiency of electrolysis.Graphical Abstract
