This invention relates to the field of fuel cell technology, and more particularly to an S-RuCr / C composite material, its preparation method, and its applications. The invention involves mixing a ruthenium source, a chromium source, a sulfur source, a hollow carbon sphere support, and a solvent, followed by a hydrothermal reaction to obtain an S-RuCr / C composite material precursor. The precursor is then calcined under a mixed atmosphere of hydrogen and argon to obtain the S-RuCr / C composite material. The preparation method of this invention is simple, as the hydrothermal reaction does not require the high temperatures of solid-state reactions (typically 800–1200°C), meeting the requirements of green chemistry and low energy consumption. Furthermore, it exhibits excellent electrocatalytic hydrogenation performance under alkaline conditions. Therefore, the S-RuCr / C composite material prepared by this invention has promising potential applications in anion exchange membrane fuel cells.
