description The invention discloses a preparation method of an ultralow-palladium-loaded Co-Ag@Pd/C oxygen reduction catalyst and belongs to the field of fuel cell catalysts. According to the preparation method of the ultralow-palladium-loaded Co-Ag@Pd/C oxygen reduction catalyst, a dispersing agent and an ethylene glycol solution are added into a flask, after the dispersing agent and the ethylene glycol solution are uniformly stirred, oleylamine is added into the flask until the oleylamine is uniformly dispersed; a cobalt chloride and silver nitrate mixed solution which is prepared by taking the ethyleneglycol and oleylamine as solvents is added into the flask, wherein the cobalt chloride and silver nitrate mixed solution has the same volume as the previously obtained mixed liquid; activated carbonpowder is added into the flask, mixing is performed, so that a homogeneous-phase solution can be obtained, and the homogeneous-phase solution is subjected to heat preservation for a certain period oftime, so that a Co-Ag/C pre
