A secondary battery includes an electrode assembly, and a case configured to accommodate the electrode assembly. At least a portion of the case includes a first insulation layer, a second insulation layer, and a capacitor between the first insulation layer and the second insulation layer, and the first insulation layer is nearer to the electrode assembly than the second insulation layer.

Secondary battery

An air supply system for a fuel cell and a fuel supply system with the same include a housing having an inlet hole and an outlet hole for respectively allowing inward and outward flow of a fluid; an air pump inserted and installed into the housing and having an inlet tube into which the fluid flows and an outlet tube through which the fluid flows out; a filtering portion installed between the inlet hole and the outlet hole within the housing and filtering particulate contaminants and chemical contaminants in the fluid; and a soundproofing member installed between the outlet tube and the outlet hole within the housing.

Air supply system for fuel cell and fuel cell system using the same

A fuel tank and a cap device for the fuel tank. The fuel tank is connected to a fuel cell and includes a tank body having a fuel opening and a pin hole for maintaining an inside pressure, a floater positioned on a surface of the fuel stored in the tank body, and an air pipe connected to the pin hole and an upper part of the floater. The cap device includes a cap body having an inside transfer path for connecting an inlet opening for introducing the fuel and an outside transfer pipe, a fixed outer cap including a connector for fixing a discharge opening into which the transfer pipe is inserted, and an elastic opening/closing section in which the cap body is elastically compressible by the connector, and wherein the inside transfer path opens during the compression.

Fuel tank and cap device thereof

There are provided a pump of a noise suppression and vibration proof structure and a fuel cell system using the same. The fuel cell system includes at least one electricity generator including an electrolyte membrane and an anode and a cathode attached to the both surfaces of the electrolyte membrane to generate electricity energy by the electrochemical reaction between fuel containing hydrogen and oxidant supplied to the anode and the cathode, a fuel supplying unit including a pump for supplying the oxidant to the electricity generator, and a fixed frame that is provided on a lower frame and to which the pump is fixed. The pump is separated from the lower frame and is fixed to and combined with the fixed frame by the belt-shaped fixing member on the side surface of the fixing frame with a buffering member interposed. Therefore, it is possible to reduce the noise and vibration of the pump.

Pump having noise-proof and vibration-proof structure and fuel cell system using the same

A direct methanol fuel cell system includes a fuel cell main body including at least one membrane-electrode assembly having an electrolyte membrane, and an anode and a cathode positioned on opposite sides of the electrolyte membrane; a fuel-supplying unit feeding a mixing tank with high concentration fuel; the mixing tank mixing and storing the fuel fed from the fuel-supplying unit and an outlet stream discharged from the fuel cell main body; a fuel feeder supplying mixed fuel stored in the mixing tank to the fuel cell main body; and a controller controlling the fuel-supplying unit to stop operating in response to a stop request signal, and controlling the fuel feeder to operate to circulate the mixed fuel via the anode of the fuel cell main body until a fuel concentration of the mixed fuel is less than or equal to a reference concentration.

Direct methanol fuel cell system and operating method thereof

A stack for a fuel cell includes a first collecting plate having a first electric polarity, a second collecting plate having a second electric polarity different from the first electric polarity, and at least one electricity generator located between the collecting plates. The at least one electricity generator is for generating electric energy due to electrochemical reaction between hydrogen and oxygen to be collected by the collecting plates. Coupling members press the at least one electricity generator in an airtight connection between the collecting plates. A terminal member protrudes from the second collecting plate and is electrically connected to the first collecting plate and insulated from the second collecting plate, such that the terminal member is used as a first terminal having the first polarity. The second collecting plate or a second terminal member may also be used as a second terminal having the second polarity.
