Abstract
Official abstract text for this publication.
A composite for a porous transport layer may include a particulate substrate including at least one selected from a group consisting of an oxide of a first metal and a second metal, and nanoparticles of a third metal formed on a surface of the particulate substrate, a sintered body thereof, and a method for preparing the same.
First claim
Opening claim text (preview).
What is claimed is: 1. A porous transport layer comprising a porous sintered body, wherein the porous sintered body comprises a sintered body of a composite for the porous transport layer, wherein the composite for the porous transport layer contains: a particulate substrate containing at least one selected from a group consisting of an oxide of a first metal and a second metal; nanoparticles of a third metal formed on a surface of the particulate substrate, wherein the particulate substrate has an average particle diameter of 20 μm to 50 μm, wherein the nanoparticles of the third metal have an average particle diameter of 10 nm to 50 nm, wherein the particulate substrate and the nanoparticles of a third metal are bound, wherein the sintered body of the composite for the porous transport layer comprises necking between the nanoparticles, wherein the nanoparticles do not form a separate layer, wherein the oxide of the first metal includes cerium (Ce) doped with at least one metal selected from a group consisting of scandium (Sc), yttrium (Y), and a lanthanide, and wherein each of the second metal and the third metal independently include titanium (Ti). 2. The porous transport layer of claim 1 , wherein the sintered body has an average pore diameter of 5 μm to 30 μm and an average porosity of 30% to 60%. 3. A water electrolysis cell or fuel cell comprising the porous transport layer of claim 1 .
