The invention discloses a structure management method of a multi-stack fuel cell power cooling system. The structure management method comprises the following steps: S1, when a cell is SOCgt; the fuel cell does not work at 80% and is independently powered by the cell; if the SOC of the battery is less than or equal to 80%, turning to S2; s2, adopting a depth deterministic strategy gradient (DDPG) to determine a stack sequence in which the multi-stack fuel cell needs to work; obtaining an intelligent agent after offline training, and implanting the intelligent agent into the VCU; s3, the multi-pile fuel cell system distributes the output power of each electric pile according to the sum of the power output by the intelligent agent; and S4, judging the serial numbers of the electric piles needing to work, recording and storing the historical working durations of the electric piles, and sequencing the device according to the historical working durations of the electric piles. According to the invention, the probl
