The high-power-density fuel cell stack comprises a rack, an air cylinder is fixedly installed on the upper portion of the rack, an elastic piece is fixedly connected to the output end of the air cylinder, a pressing plate is fixedly installed at the end, away from the air cylinder, of the elastic piece, and a plurality of single cells are placed in the middle of the rack; the plurality of single cells are matched with the pressing plate for pressing and assembling to form a high-power-density fuel cell stack; a limiting assembly is further arranged in the rack. When pressure is applied to the output end of the air cylinder, the elastic piece elastically deforms, and the pressure is transmitted to the pressing plate, so that the pressing plate presses the single battery. Through the pressing effect of the pressing plate, the single cells can be tightly assembled together to form a high-power-density fuel cell stack. When the linkage frame moves, the first toothed plate drives the gear to rotate, and when the g
