Abstract
The embodiments provide an electrode catalyst layer for an electrolysis cell, and also an electrolysis cell and a carbon dioxide electrolysis apparatus comprising that layer. The catalyst layer has a controlled porous structure, and can realize a high partial current density. The catalyst layer of the embodiment comprises carbonous catalyst carriers, a metallic catalyst loaded on the carriers, and an ion-conductive material. The catalyst layer contains pores of 5 to 200 μm diameters, and the pores have a volume per weight of the catalyst layer in the range of 3.0 to 10 mL/g in total.
