摘要： A method for controlling an electric heater of a vehicular heating, ventilation, and air conditioning (HVAC) system includes turning on the electric heater; determining whether an ambient air temperature of a vehicle is higher than or equal to a threshold ambient air temperature, and a battery temperature is lower than or equal to a threshold battery temperature; determining whether battery efficiency is lower than or equal to threshold efficiency when the ambient air temperature of the vehicle is higher than or equal to the threshold ambient air temperature, and the battery temperature is lower than or equal to the threshold battery temperature; and turning off the electric heater when the battery efficiency is lower than or equal to the threshold efficiency, wherein the electric heater is configured to receive electric energy from the battery.

摘要： Disclosed are an electrode gas diffusion layer assembly (EGA) and a fuel cell stack including the same. The content of the binder in the electrode and the content of the binder in the adhesive layer that attaches the electrode to the gas diffusion layer (GDL) may be optimized. Thus, it is possible to reduce the occurrence of flooding and the deterioration in durability/performance caused by a dry atmosphere in the EGA including the electrode and the adhesive layer, so that the output density per unit area is improved while the trade-off is minimized.

摘要： A method for manufacturing a membrane-electrode assembly (MEA) is provided. In particular, first and second sub-gasket sheets are continuously supplied and an electrode membrane sheet having gaps formed therein so that the amount of an electrolyte membrane used is reduced is discontinuously supplied. Thus, the minimum length of the electrolyte membrane protrudes between sub-gaskets and the electrolyte membrane together with electrode catalyst layers is bonded to the sub-gaskets

摘要： An turbocharger for a vehicle is provided. The turbocharger includes a shaft that has a hollow aperture at an inside thereof and an outer circumferential surface of the shaft includes an inlet aperture and an outlet aperture which communicate with the hollow aperture. A turbine wheel is integrally installed at the shaft and a hollow groove formed in the wheel communicates with the hollow aperture. A center housing includes a shaft groove in which the shaft is rotatably installed. The center housing includes an oil passage to which oil is supplied from an oil pipe, an air passage to which air is supplied from an air tank, and an injection passage extending to the shaft groove while being connected to the oil and air passages. An oil valve and an air valve are installed in the oil and air passages, respectively, to selectively open/close flow of a fluid.

摘要： A fuel cell includes an electrolyte membrane, first and second electrode layers disposed on first and second surfaces of the electrolyte membrane, respectively, the second surface being opposite to the first surface. One of the first and second electrode layers is an anode electrode layer and the other is a cathode electrode layer. Additionally, first and second gaskets are disposed on the first and second surfaces of the electrolyte membrane, respectively, to be adjacent to an edge of the electrolyte membrane. The first electrode layer includes a first main electrode layer disposed on the first surface of the electrolyte membrane and inside the first gasket and a first sub-electrode layer having a first portion inserted between the first main electrode layer and the electrolyte membrane and a second portion inserted between the first gasket and the electrolyte membrane.
