  • Patent number: 10576485
    Abstract: As an ejector of the present disclosure and a cooling apparatus having the same include a suction guide unit at least partially having a curved surface so that the ejector guides a flow of a refrigerant, a structure is improved and thus a flow loss can be reduced. Also, through the improved structure, a mixture rate between a refrigerant passing through a nozzle unit and a refrigerant passing through a suction unit is improved, so that pressure rising efficiency can be increased to reduce a compressor load, and thus energy efficiency can be increased due to an increase in efficiency of the ejector.

  • Patent number: 9059470
    Abstract: A cathode for a fuel cell includes a gas diffusion layer contacting with a separator having a channel and a catalyst layer interposed between the gas diffusion layer and an electrolyte membrane. The catalyst layer of the cathode has two portions with different water-repelling properties, and a portion of the catalyst layer that does not face a channel has a higher water-repelling property than a portion that faces a channel. This cathode controls a water-repelling property of the catalyst layer differently according to locations, so it is possible to keep an amount of moisture in an electrode in a suitable way and to restrain generation of flooding, thereby improving the performance of the cell.

  • Publication number: 20110020724
    Abstract: An electrode for a fuel cell includes a gas diffusion layer contacting with a separator having a channel and a catalyst layer interposed between the gas diffusion layer and an electrolyte membrane. The catalyst layer of the electrode has two portions with different hydrophilicities. A portion of the catalyst layer that faces a channel has a higher hydrophilicity than a portion that does not face a channel. This electrode may control hydrophilicity of the catalyst layer differently according to locations, so it is possible to keep an amount of moisture in an electrode in a suitable way, thereby improving the performance of the cell.

  • Publication number: 20100304269
    Abstract: The present invention relates to an electrode for a fuel cell including a catalyst layer that includes a catalyst portion containing a plurality of first catalyst particles dispersed in an ionomer binder resin; and an ionomer portion containing a plurality of second catalyst particles dispersed in an ionomer binder resin, and having a lower concentration of catalyst particles than the catalyst portion, wherein the ionomer portion has a shape of a wall or plural pillars in the catalyst portion. The electrode for a fuel cell according to the present invention has a separate ionomer portion in the catalyst layer, and thus has excellent ion conductivity in an electrode layer and the remarkably improved reaction surface area to enhance the performance of the fuel cell.
