Title:
CONDUCTIVE FILM, GAS DIFFUSION LAYER FOR FUEL CELLS, CATALYST LAYER FOR FUEL CELLS, ELECTRODE FOR FUEL CELLS, MEMBRANE ELECTRODE ASSEMBLY FOR FUEL CELLS, AND FUEL CELL
Document Type and Number:
WIPO Patent Application WO/2015/098089
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a conductive film which has excellent electrical conductivity and gas diffusibility, and which is useful as a material for forming a gas diffusion layer or a catalyst layer for electrodes of fuel cells, and the like. A conductive film according to the present invention contains: carbon nanotubes having an average diameter (Av) and a standard deviation (σ) of the diameters satisfying relational expression 0.60 > (3σ/Av) > 0.20; and a conductive carbon that is different from the carbon nanotubes. The mass ratio of the carbon nanotubes to the conductive carbon in the conductive film is from 1/99 to 99/1.
