Abstract

An improved fluid recycling apparatus and a fuel cell system comprising the same effectively recycle moisture contained in fluid circulating in a fuel cell system and operate independent of orientation. The fluid recycling apparatus includes an electric penetration pump and a gas/liquid separation unit. The electric penetration pump has first and second electrodes and an electric penetration layer interposed between the first and second electrodes. The electric penetration pump directs a liquefied fluid through an electric fluid passage formed in the electric penetration layer by applying a voltage between the first electrode and the second electrode. The gas/liquid separation unit is disposed upstream of the electric fluid passage, contacting the electric penetration pump, and comprises a porous material that can absorb the liquefied fluid. The gas/liquid separation unit comprises at least one fluid inflow hole through which a mixture of a gaseous fluid and a liquefied fluid is introduced, and at least one gas discharge hole communicating with the fluid inflow hole configured for discharging the gaseous fluid.
