1. A gas diffusion electrode for use in a membrane electrolysis cell, the gas diffusion electrode comprising:
a diffusion layer configured to diffuse a gas comprising oxygen;
a first catalyst layer disposed on a surface of the diffusion layer, the first catalyst layer having a hydrophilicity greater than that of the diffusion layer and being capable of transporting negative ions; and
an anion exchange membrane disposed on a surface of the first catalyst layer, the anion exchange membrane being configured to exchange ions from the first catalyst layer to an opposed surface of the anion exchange membrane.
