Abstract: The present disclosure relates to an IrO2 electrodeposited 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 (IrO2) layer on the porous Ti layer. The IrO2 layer may be uniformly deposited on a porous Ti layer through an electrolysis process, and the electrodeposited IrO2 layer 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.
