  • 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: 20100295732
    Abstract: System and method for removing channel phase error in a phase comparison direction finder. By using this system, the phase error, generated in the channel path in finding the direction by using the phase comparison direction finder, can be injected into the receiving channel and removed by using the frequency and intensity of the signal stored in the PDW table. Furthermore, the direction finding correction look-up table can be made using only radiation correction of the antenna unit of the direction finder and channel correction can be carried out without calibrating the direction finder for the direction finding correction look-up table when devices are replaced in the channel of receiving path of the direction finder.
