PASTE FOR DIFFUSION LAYER FORMATION AND PRODUCTION METHOD THEREOF AND PRODUCTION METHOD OF GAS DIFFUSION LAYER

摘要

The paste for diffusion layer formation used for formation of a GDL for a fuel cell contains a solvent, and conductive particles, a first surfactant having a first decomposition temperature and a second surfactant having a second decomposition temperature that is lower than the first decomposition temperature, all of which are dispersed in the solvent. The paste for diffusion layer formation contains a lower amount of the first surfactant than the second surfactant on a weight basis.

1. A paste for diffusion layer formation used for formation of a gas diffusion layer for a fuel cell comprising:
a solvent; conductive particles dispersed in the solvent; a first surfactant which is dispersed in the solvent and has a first decomposition temperature at which the first surfactant is decomposed; and a second surfactant which is dispersed in the solvent and has a second decomposition temperature at which the second surfactant is decomposed, the second decomposition temperature being lower than the first decomposition temperature, wherein the paste for diffusion layer formation contains a lower amount of the first surfactant than the second surfactant on a weight basis.
