Abstract

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.
