Fuel cell performance of templated Ru/Se/C-based catalysts

The catalytic activity of highly porous Ru/Se/C-based catalysts was investigated. Fuel cell measurements were carried out in a 5 cm2 cell using pure hydrogen and oxygen at a temperature of 75 °C and ambient pressure. Maximum power densities of 100, 144 and 150 mW cm−2 were observed for membrane electrode assemblies (MEA) containing of 0.04, 0.12 and 0.22 mg cm−2 ruthenium, respectively. The catalysts were further characterized by high resolution transmission electron microscopy (HRTEM) and X-ray photoelectron spectroscopy (XPS).
