Abstract

To enhance Pt utilization in the fuel-cell electrode by microscopically controlling the distribution of liquid electrolytes around Pt catalysts, the amphiphilic surfactant tergitol phosphate was synthesized and introduced into the fuel-cell electrode. The chemical structure of the surfactant was determined by 1H-nuclear magnetic resonance, and its adsorption property on Pt–C catalyst was ascertained by Fourier transform infrared analysis. The electrode into which the amphiphilic surfactants were incorporated showed improved performance, and especially the amphiphilic surfactant with polyethylene oxide, NPE10-OPO(OH)2, produced higher cell performance.
