摘要： A cooling method for a fuel cell using a heat exchanger is provided. The method comprises the steps of: providing an ion exchanger in a circulation system for the cooling fluid; decreasing ion concentration in the cooling fluid by circulating the cooling fluid through the fuel cell and the ion exchanger when the temperature of the cooling fluid is below a thermostat operating temperature; distributing a portion of the cooling fluid discharged from the fuel cell, mixing the portion of the cooling fluid returning from the heat exchanger with another portion of the cooling fluid whose ion concentration has been decreased in the previous step, and returning the cooling fluid mixture to the fuel cell, when the temperature of the cooling fluid is approaching the thermostat operating temperature; and cooling the fuel cell by circulating the cooling fluid through the fuel cell and the heat exchanger after the temperature of the cooling fluid reaches the thermostat operating temperature. By using this cooling method, the cooling fluid having a high conductivity is not distributed to the fuel cell.

摘要： In a cooling device for a fuel cell, a primary cooling liquid discharged from a heat exchange device 3 is partially flowed to an ion exchange device 15 through a communication passage 11B. A flow rate regulator 14 provided in the communication passage 11B regulates the flow rate of the primary cooling liquid flowed into the ion exchange device 15. Accordingly, even if the electricity demanded to be outputted from the fuel cell increases or decreases, it is possible to manage conductivity in the primary cooling liquid and useless consumption energy can be reduced to a minimum.

摘要： A gasoline direct-injection engine includes a cavity provided in a top portion of a piston and constituting a portion of a combustion chamber defined between a cylinder head and the top portion of the piston, a fuel injection valve mounted in the cylinder head for injecting gasoline directly into the combustion chamber, and a spark plug also mounted in the cylinder head to face the combustion chamber. In this gasoline direct-injection engine, the fuel injection valve facing a substantially central portion of a ceiling surface of the combustion chamber is mounted in the cylinder head to have an axis substantially parallel to an axis of the piston, and the cavity provided in the top portion of the piston and disposed below the fuel injection valve and the spark plug is defined so that it is deeper in an area corresponding to the spark plug than in an area corresponding to the fuel injection valve. Thus, it is possible to achieve a stable lean laminar burn in wide ranges of rotational speed and load of the engine, thereby providing an improvement in fuel consumption and an enhancement in nature of an exhaust gas.
