Beschreibung
Zusammenfassung:	Disclosed herein is a method for producing a porous structure electrode (20) with gas permeability and liquid impermeability, comprising the following steps: Step 1: mixing a catalytic material having hydrophilicity, a carbon nanotube material, a material with a hydrophilic group, and a carbon black material to form a first slurry, wherein the carbon nanotube material has a specific surface area equal to or greater than the carbon black material; Step 2: mixing the first slurry with an emulsified material to form a second slurry; Step 3: obtaining a film material through a film forming process; Step 4: heating the film material to a first temperature to remove solvent in the film material; Step 5: Repeating steps 3 to 4; and Step 6: heating the film material to a second temperature to remove liquid in the film material, thereby leaving pores in the film material, and allowing the film material to solidify.
