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.

Abstract: A polybenzimidazole based polymer in which substituted or non-substituted benzyl groups are introduced to the two nitrogen atoms of benzimidazole ring. The benzimidazole ring is not decomposed by the attack of hydroxide ions but shows excellent alkali resistance, and thus maintains high ion conductivity. The polybenzimidazole based polymers are particularly useful for not only solid alkali exchange membrane fuel cells (SAEMFC) but also various industrial fields in which polybenzimidazole based polymers are used.

Abstract: Provided is an electrocatalyst for anion exchange membrane water electrolysis, including a carbonaceous material, and nickel electrodeposited on the carbonaceous material, wherein nickel is partially substituted with platinum and the substitution with platinum provides increased hydrogen evolution activity as compared to the same electrocatalyst before substitution with platinum. Also provided are a method for preparing the electrocatalyst and an anion exchange membrane water electrolyzer using the same. The nickel electrocatalyst coated with an ultralow loading amount of platinum for anion exchange membrane water electrolysis shows excellent hydrogen evolution activity and has a small thickness of catalyst, thereby providing high mass transfer and high catalyst availability. In addition, the electrocatalyst uses a particle-type electrode to facilitate emission of hydrogen bubbles generated during hydrogen evolution reaction and oxygen bubbles generated during oxygen evolution reaction, and requires low cost for preparation to provide high cost-efficiency.
