    摘要: 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.

    摘要: A fuel cell system comprises a reformer for generating hydrogen from fuel, at least one electricity generator for generating electric energy through an electrochemical reaction between hydrogen and oxygen, a fuel supply unit for supplying the fuel to the reformer and an oxygen supply unit for supplying oxygen to the electricity generator. The reformer includes a main body which has an inner space with a reformer inlet and a reformer outlet. A reaction section is disposed within the inner space of the main body. The reaction section includes a heat-generating element for generating thermal energy from externally applied energy such as electrical current. The heat-generating element has a corrugated structure with a catalyst layer formed on the surface. The corrugated structure defines a plurality of flow passages for the fuel and encourages both even flow distribution and turbulent flow.
