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.

Composite for porous transport layer, sintered body thereof, and method for preparing the same

The present disclosure relates to a fuel cell stack having a cathode-side separator and an anode-side separator which are made of different materials to prevent performance degradation of stacks and corrosion and damage of components. A fuel cell stack according to exemplary embodiments of the present disclosure may have multiple unit cells stacked therein, in which each unit cell of the multiple unit cells may include: a membrane electrode assembly (MEA); a pair of gas diffusion layers (GDLs) disposed on opposite surfaces of the MEA; and an anode-side separator and a cathode-side separator disposed to face each other, the MEA and the pair of GDLs being disposed therebetween, in which the cathode-side separator has a corrosion resistance higher than a corrosion resistance of the anode-side separator.

Fuel cell stack

A fuel cell and a method for producing the same are provided. The fuel cell includes a membrane electrode assembly and a gas diffusion layer that is disposed at each of opposite surfaces of the membrane electrode assembly, and includes a plurality of compressed parts that are formed by pressure at positions spaced out at predetermined intervals on the gas diffusion layer. The fuel cell further includes a separator that is in contact with an outer surface of the gas diffusion layer, and has a plurality of land parts that protrude toward the gas diffusion layer, and a plurality of channel parts that form flow paths between the land parts. The land parts respectively protrude toward the compressed parts of the gas diffusion layer to come in contact with the compressed parts.

Fuel cell and method for producing the same

A display device, including: a display panel configured to display an image through a frontal surface thereof; and a window substrate disposed on the frontal surface of the display panel. The window substrate includes at least two sheets of base substrates. The display device may also include an ultraviolet blocking layer. The ultraviolet blocking layer may be disposed between the at least two base substrates.
