Polymer exchange membrane fuel cell (PEMFCs) is expected to be the promising candidate as the future clean energy sources. Especially, it is considered that the PEMFCs are suitable for applying to the transportation because of its various advantages such as high-power density, easy scale up and immediate response to change in the demand for power. However, due to the high cost of fuel cell system, it is difficult to commercialize of fuel cell automobiles. The system cost is usually depending on the usage of PGM catalyst in MEA. Herein, PtCu/C catalyst were synthesized by using sputtering method to reduce the amount of Pt which is occupying a large portion of the system cost. First, various ratio of PtCu nanoparticles were carried out onto the powder substrate by adjusting the sputter gun power. After then nanoparticles were transferred to carbon. Through the heat treatment and acid treatment, we can get mesoporous structured PtCu/C catalysts. This PtCu alloy catalyst shows similar or higher oxygen reduction reaction activity then that of commercial Pt/C even though the amount of Pt is much lower.
