Tungsten carbide modified high surface area carbon as fuel cell catalyst support

► Phase pure WC nanoparticles with a good coverage were synthesized on high surface area carbon black. ► The corrosion resistance of carbon black was improved by 2-fold with a surface modification by phase pure WC particles. ► WC modified carbon support was tested in a PEM fuel cell for the first ti...
