This application relates to a spray humidification device and a fuel cell system. The spray humidification device includes: a main shell having an evaporation chamber and a turbulence chamber, the evaporation chamber being divided into multiple independent spray chambers, which are connected to the turbulence chamber; multiple spray nozzles disposed on the main shell, each nozzle connected to a spray chamber and spraying liquid water into the spray chamber, the liquid water being capable of vaporizing into gaseous water; multiple turbulence plates spaced apart in the turbulence chamber, the turbulence plates being used to turbulent the unvaporized liquid water and gaseous water and air; and an output pipe disposed at one end of the main shell and connected to the turbulence chamber, the output pipe also being connected to the cathode inlet of the fuel cell stack, for inputting gaseous water and air into the cathode inlet. This ensures atomization effect and prevents liquid water accumulation, thereby preventing liquid water from entering the fuel cell stack and causing flooding, thus preventing fuel cell system malfunction.
