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 plate type fuel cell system includes: an electric generator including a membrane-electrode assembly having a plurality of anode electrodes and a plurality of cathode electrodes arranged on opposite surfaces of a proton-exchange membrane and spaced apart from each other; an anode separator facing the plurality of anode electrodes and having a fluid channel adapted to receive a hydrogen containing fuel; a cathode separator facing the plurality of cathode electrodes and having an air ventilating hole; a fuel distributor having an accommodating part defined by a rib to accommodate the anode separator and adapted to distribute the hydrogen containing fuel to each of the plurality of anode electrodes, the rib being partially cut out to define a rib cutting part; and a sealing member contained within the rib cutting part. With this configuration, reaction fluid, such as a hydrogen containing fuel, is effectively prevented from leaking through the rib cutting part or a frame cutting part, thereby enhancing the stability of a stack and the power generation efficiency of the fuel cell system.

Fuel cell system

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.
