Fuel recycling apparatuses and fuel cell systems using the same are provided. The fluid recycling apparatus includes a porous member having first and second ends, a first electrode coupled to the first end of the porous member, a second electrode coupled to the second end of the porous member, and a power supplier for applying a constant voltage between the first electrode and the second electrode. The porous member moves a liquid from the first end of the porous member to the second end of porous member and discharges a gas under the voltage applied by the power supplier.
