Energy storage device

An apparatus for preventing moisture condensation includes a fuel cell stack and an enclosure in which the fuel cell stack is disposed. A heater and a temperature sensor are provided in the enclosure. A controller is configured to control the heater to be turned on when an insulation resistance between the fuel cell stack and the enclosure is less than a preset resistance value. The controller controls the heater not to be turned on when a surface temperature of the enclosure measured by the temperature sensor exceeds a preset temperature.

Apparatus and method for preventing moisture condensation

A separator for a fuel cell includes a channel having a passage that is a flow path of a reaction gas, a manifold part formed at a peripheral of the channel and communicating with the passage such that the reaction gas is introduced into and discharged from the channel, and a connector connecting the channel and the manifold part such that the reaction gas flows between the channel and the manifold part. The manifold part includes an inlet manifold through which the reaction gas is introduced into the channel and formed at a lower portion of the channel, and an outlet manifold configured to discharge the reaction gas from the channel to an outside of the fuel cell and formed at an upper portion of the channel.

A cooling water direct injection type fuel cell is provided. The fuel cell includes an air-side separator that has an air channel through which air flows, and a cooling water inlet aperture that is formed on an introduction portion of the air channel. A hydrogen-side separator is joined with the air-side separator and has a protrusion that is inserted into the cooling water inlet aperture. The protrusion has a diameter less than a diameter of the cooling water inlet aperture to form a gap between an outer circumferential surface of the protrusion and an inner circumferential surface of the cooling water inlet aperture. Cooling water drawn into space between the junction surfaces of the air-side separator and the hydrogen-side separator is discharged through the gap between the protrusion and the cooling water inlet aperture, is mixed with introduced air, and then is drawn into the air channel.

Cooling water direct injection type fuel cell

A fuel cell stack enclosure includes: a lower housing disposed under a fuel cell stack and having a bottom plate portion provided with a water outlet therein; a sealing cap closing the water outlet from an outside of the lower housing; and an elastic member elastically pulling the sealing cap toward the bottom plate portion of the lower housing.

Fuel cell stack enclosure

The present invention features a fuel cell stack that preferably includes an electricity generating assembly having a plurality of unit cells that are suitably disposed one after another; a pair of end plates pressedly disposed respectively at upper and lower ends of the electricity generating assembly; and a joining device suitably engaging the end plates by a rope, where pressure is applied to the electricity generating assembly by means of tension of the rope, and the length and tension of the rope is suitably controlled.

Joining device for fuel cell stack and fuel cell stack provided with the same

A humidifier includes an inlet assembly provided in an air exhaust pipe, through which water-supersaturated exhaust gas is discharged from a fuel cell stack, to supply water condensed from the exhaust gas to the fuel cell stack and an outlet assembly provided in an air supply pipe, through which a reactant gas to be humidified and supplied to the fuel cell stack passes, to supply the water transferred through a pumping pipe to the air supply pipe such that the reactant gas is humidified. A pumping pipe including a porous material disposed therein along with electrodes are disposed between the inlet assembly and the outlet assembly so that the water is transferred through a capillary path in the porous material via a pumping force by electroosmosis when the electrodes apply a voltage.

Humidifier including an auxiliary humidifier utilzing electroosmosis

The present invention provides a method of assembling a fuel cell stack, in which a fixing block and a fixing pin are used to assemble the fuel cell stack instead of a bolt, thereby reducing the time and process required for assembly of the fuel cell stack, enabling an assembly process using an automated device to be realized, and facilitating mass production.
