Gas diffusion electrode
View Patent ↗The present invention provides a gas diffusion electrode having: an electrode substrate; and a catalyst layer containing a hydrophilic catalyst and a hydrophobic binder, which is carried on the electrode substrate, wherein the electrode substrate contains at least one carbon material selected from a carbon cloth, a carbon paper, a foamed carbon material, and a sintered carbon material.
1. A gas diffusion electrode comprising:
an electrode substrate; and
a catalyst layer containing a hydrophilic catalyst and a hydrophobic binder, which is carried on the electrode substrate,
wherein the electrode substrate is formed of woven carbon fabric, and
wherein the electrode substrate is further coated with a conductive metal, or a fiber or a particle of the conductive metal is mixed in the electrode substrate in an amount of 1 to 50% by volume of the substrate.
2. The gas diffusion electrode according to claim 1 ,
wherein the hydrophilic catalyst or the conductive metal is a silver or a silver alloy.
