Abstract
The present disclosure relates to an IrOelectrodeposited porous titanium composite layer of a polymer electrolyte membrane water electrolysis apparatus serving as both a diffusion layer and an oxygen electrode, the apparatus including: a porous titanium (Ti) layer; and an electrodeposited iridium oxide (IrO) layer on the porous Ti layer. The IrOlayer may be uniformly deposited on a porous Ti layer through an electrolysis process, and the electrodeposited IrOlayer may play multiple roles as not only a catalyst layer toward oxygen evolution reaction (OER) on the surface of the Ti layer, but also a corrosion-protection layer which prevents an inner Ti layer from corrosion.
