Abstract
Disclosed is a gas-liquid separator capable of allowing carbon dioxide to be exhausted to the atmosphere so as to recover and recycle only unreacted fuel discharged from an electric generator, and a fuel cell system having the same. The fuel cell system includes an electric generator to generate electricity by electrochemical reaction between hydrogen and oxygen, a fuel feeder to supply hydrogen containing fuel to the electric generator, an oxidant feeder to supply oxygen to the electric generator, and a recovering unit to recover unreacted fuel generated during the electrochemical reaction in the electric generator and supply the unreacted fuel to the fuel feeder. The recovering unit comprises a frame structure, and a gas-liquid separation film partially surrounding the frame structure. The gas-liquid separator forms a flow space inside the frame structure. Accordingly, the unreacted fuel, which is not participated in the oxidation-reduction reaction between the hydrogen containing fuel and the oxidant, is recovered and recycled while excluding carbon dioxide, so that power generation efficiency of the fuel cell system is enhanced.
