内容記述
Pt-C slurries used for production of polymer electrolyte fuel cell electrode were evaluated to control its microstructure and properties. Slurries were prepared by changing the particle concentration and additive dosages of ethanol and Nafion. Centrifugal sedimentation curves, zeta potential and flow curves of the prepared slurries were measured. It was found that the Pt-C particles dispersion and flocculation state could be changed by adjusting the additive dosage of ethanol probably due to change of hydrophilicity of particle surface. However, after addition of Nafion, the difference of particle dispersion state became quite small suggesting another factor should affect the fuel cell properties in this system.
