Document Type and Number:
Japanese Patent JP2805458
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a production method of a gas diffusion electrode which has high strength, can be made in a large size and has a high charge collection efficiency and excellent electrode performance in a simple process with good workability by a suitable method for mass production. SOLUTION: A catalyst having an electrode catalytic effect is mixed with hydrophilic carbon black, water-repellent carbon black, water and polytetrafluoroethylene fine particles, and filtered if necessary, to obtain a slurry. The obtd. slurry is applied on one surface or both surfaces of an electric conductive porous body (such as a metal porous body) to fill the pores without drying. Then the surfactant is removed and the porous body is dried and sintered to obtain a gas diffusion electrode.
