Hydrogen fuel cells are increasingly seen as a potential answer to energy needs, thanks to their high energy conversion efficiency and clean, zero-emission function. Nonetheless, the slow pace of the cathodic oxygen reduction reaction and the high costs associated with platinum catalysts have restricted their widespread use. This study employed magnetron sputtering and ion implantation techniques to address the challenge of preparing Cu-N-C and Cu(Pd)-N-C catalysts. Experiments were conducted using glass carbon as the substrate. Cu-N-C catalyst films were successfully prepared by adjusting parameters: the ratio of Ar and N2 , sputtering power, and sputtering time etc Subsequently, Cu(Pd)-N-C catalysts were synthesized by implanting different doses of Pd metal into the Cu-N-C films using ion implantation technology. The catalysts\u2019 morphology, structure, and elemental composition were analyzed using SEM, EDS, XRD, and XPS characterization techniques. Electrochemical performance tests revealed that, compared to the Cu-N-C catalyst without Pd implantation, the Cu(Pd)-N-C catalyst at an ion implantation dosage of \n \n\n<\/jats:tex-math>\n \n 1<\/mml:mn>\n \u00d7<\/mml:mo>\n \n \n 10<\/mml:mn>\n <\/mml:mrow>\n \n 17<\/mml:mn>\n <\/mml:mrow>\n <\/mml:msup>\n \n \n \n cm<\/mml:mi>\n <\/mml:mrow>\n \n \u2212<\/mml:mo>\n 2<\/mml:mn>\n <\/mml:mrow>\n <\/mml:msup>\n <\/mml:math>\n <\/jats:inline-formula> exhibited a significant enhancement in ORR performance, with the Eonset<\/jats:sub> and E1\/2<\/jats:sub> being \n \n\n<\/jats:tex-math>\n \n 98<\/mml:mn>\n \n mV<\/mml:mi>\n <\/mml:math>\n <\/jats:inline-formula> and \n \n\n<\/jats:tex-math>\n \n 163<\/mml:mn>\n \n mV<\/mml:mi>\n <\/mml:math>\n <\/jats:inline-formula> higher, respectively.
