Abstract: Some embodiments of the disclosures provide an anode recovery system of a fuel cell. The anode recovery system includes a gas supply unit connected to a power generation unit, a gas-liquid separator connected to the power generation unit and a first anode gas recovery control component; and a storage tank connected to the gas-liquid separator and a cathode recovery system. The gas supply unit is configured to provide anode gas to the power generation unit. A first part of unreacted anode gas from the power generation unit mixes with the anode gas and flows back to the power generation unit sequentially via the gas-liquid separator and the first anode gas recovery control component. A second part of the unreacted anode gas and generated water are discharged from the power generation unit to the storage tank and is further discharged to the cathode recovery system.
