The invention relates to an integrated glue injection sealing fuel cell single cell structure, a glue injection mold, a manufacturing process and a cell stack, and the integrated glue injection sealing fuel cell single cell structure comprises an anode plate, a membrane electrode and a cathode plate which are sequentially stacked along the same direction to form a single cell frame structure, a plurality of glue injection holes are formed in the single cell frame structure, sealant is injected through the glue injection holes to form a sealing structure, and the single cell frame structure is hermetically connected through the sealing structure to form the integrated glue injection sealing fuel cell single cell structure. The single battery structure is formed through one-time glue injection integrated sealing connection, so that the sealing performance and the production efficiency of the single battery are effectively improved, the assembly process of the single battery is simplified, the production cost of
