The invention provides an electric pile life prediction method and device of a fuel cell system, a cloud platform and a medium, and belongs to the technical field of fuel cells. The method comprises the following steps: acquiring electric pile key data of a fuel cell system; determining a target stack voltage corresponding to each actual stack current from the volt-ampere characteristic curve data; determining a first predicted life of the fuel cell system according to the plurality of actual stack voltages and the plurality of target stack voltages; determining a second predicted life of the fuel cell system according to the total operation time of the fuel cell system and the designed life of the stack; determining a third predicted life according to the stack calendar life and the stack quality guarantee time of the fuel cell system; and determining the final predicted life of the fuel cell system according to the first predicted life, the second predicted life and the third predicted life, and calculating
