The invention relates to a single-cell polar plate structure of a fuel cell. The single-cell polar plate structure comprises a polar plate body, a medium channel, a first gas channel boss and a glue injection sealing groove, sealant is injected into the sealant injection sealing groove, the sealant avoids the first communication channel through the first gas channel boss to form a sealing structure, and the phenomenon that the smoothness of a medium between the first gas channel and the flow channel area is affected is avoided; the sealing glue can form an integral sealing structure on the polar plate, and meanwhile, the second gas channel, the cooling water channel and the first gas channel can be separated, so that the sealing performance is ensured, and media in the medium channels are prevented from leaking inwards; by adopting the polar plate structure provided by the invention to adaptively produce the single battery, the sealing performance and the production efficiency of the single battery can be eff
