NOVELTY - An electronic apparatus system comprises electronic apparatus, and fuel cell apparatus. The electronic apparatus comprises a cabinet and a heat generating component in the cabinet. The fuel cell apparatus comprises electromotive module, fuel tank, circulation system, and gas-liquid separator (142). The electromotive module comprises an anode and a cathode. The electromotive module generates electricity by a chemical reaction. The fuel tank stores a fuel. The circulation system comprises a fuel channel (146) and air channel (147).    USE - Electronic apparatus system for portable computer.    ADVANTAGE - The system provides improved electricity generation efficiency, maintains high separation performance of gas-liquid separator provides effectively separation of gas in two phase fluid without increasing power consumption of portable computer and without increasing its size, prevents occurrence of dewed water, and is simple.    DETAILED DESCRIPTION - An electronic apparatus system comprises electronic apparatus, and fuel cell apparatus. The electronic apparatus comprises a cabinet and a heat generating component in the cabinet. The fuel cell apparatus comprises electromotive module, fuel tank, circulation system, and gas-liquid separator (142). The electromotive module comprises an anode and a cathode. The electromotive module generates electricity by a chemical reaction. The fuel tank stores a fuel. The circulation system comprises a fuel channel (146) and air channel (147). The fuel channel circulates a fuel supplied from the fuel tank through the anode of the electromotive module. The air channel supplies air through the cathode of the electromotive module. The gas-liquid separator is between a flow-out end of the electromotive module and the fuel tank in the fuel channel. The gas-liquid separator separates a gas-liquid two phase fluid discharged from the anode to a liquid and gas, thermally coupled to the heat generating component, and is to be heated by the heat of the heat generating component. The gas-liquid separator comprises a gas permeable membrane, and external vessel. The system includes radiator. A portion of the external vessel thermally coupled to the heat generating component is formed of metal.
