Method of producing a vapor-permeable and liquid-impermeable porous structure electrode

A method for manufacturing a porous structure electrode 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, and stirring the 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, and stirring the second slurry;
• step 3:
• obtaining a film material from the second slurry 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 at least once;
• 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, wherein the second temperature is higher than the first temperature, and the second temperature is between 200° C. and 500° C.;
• wherein a weight percentage of the catalytic material in the first slurry is in a range of 50% to 85%, a weight percentage of the carbon nanotube material in the first slurry is in a range of 0.01% to 10%, a weight percentage of the material with the hydrophilic group in the first slurry is in a range of 7% to 30%, a weight percentage of the carbon black material in the first slurry is in a range of 5% to 30%, and a weight percentage of the emulsified material in the second slurry is in a range of 2% to 20%.
