METHOD FOR MANUFACTURING GAS DIFFUSION LAYER FOR FUEL CELL AND GAS DIFFUSION LAYER MANUFACTURED THEREBY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240105963 titled 'METHOD FOR MANUFACTURING GAS DIFFUSION LAYER FOR FUEL CELL AND GAS DIFFUSION LAYER MANUFACTURED THEREBY

Simplified Explanation

The abstract describes a method for manufacturing a gas diffusion layer for a fuel cell by impregnating carbon nanotubes into Korean paper to enhance electroconductivity.

• Korean paper is used as a support in the manufacturing process.
• Carbon substance is dispersed in a solvent to form a dispersion.
• The support is coated with the dispersion.
• The dispersion-coated support is thermally treated to fix the carbon substance.
