MEMBRANE ELECTRODE ASSEMBLY FOR ANION EXCHANGE MEMBRANE WATER ELECTROLYZER AND METHOD OF MANUFACTURING MEMBRANE ELECTRODE ASSEMBLY FOR ANION EXCHANGE MEMBRANE WATER ELECTROLYZER

摘要

The present invention provides a membrane electrode assembly for a proton exchange membrane water electrolyzer, comprising: an oxygen electrode including an iridium oxide (IrO_2) layer which is an oxygen electrode layer electrolytically plated on a titanium (Ti) layer as a diffusion layer; a hydrogen electrode having a hydrogen electrode layer formed on the diffusion layer; and an electrolyte membrane positioned between the oxygen electrode layer and the hydrogen electrode layer. Some of pores of the Ti layer, which is the diffusion layer, are filled with the electrolyte of the electrolyte membrane. Accordingly, the electrolyte/electrode interface can be increased.
