20080305376 | ELECTRODE FOR FUEL CELL AND FUEL CELL EMPLOYING THE SAME - Provided are an electrode for a fuel cell and a fuel cell employing the electrode, the electrode comprising a catalyst layer including: a catalyst; a material having stronger binding force to anions than the catalyst; and a binder. According to the electrolyte for a fuel cell, electrochemical surface area of the catalyst is maximized, and thus efficiencies in oxygen reduction reaction (ORR) and hydrogen oxidation reaction (HOR) of the catalyst are improved. Thus, a fuel cell having improved power generation efficiency may be prepared by employing the electrode. | 12-11-2008 |
20080270537 | COMMUNICATION SYSTEM AND REPLY METHOD THEREOF - A communication system and a reply method thereof that enable various types of replies to be attached to a user's article posted on a web page is provided, whereby a user can easily check the user's article having a reply posted on the web page. The method includes posting a user's article of a user page on a web page, connecting to the web page and attaching a reply to the posted user's article, and displaying the user's article having the reply on the user page when a request for displaying the user's article on the user page is received. | 10-30-2008 |
20080268871 | SYSTEM AND METHOD FOR PROVIDING LOCATION BASED SERVICES IN A MOBILE COMMUNICATION SYSTEM - A system for providing LBS in a mobile communication system. An AAA server manages information on an anchor authenticator (AA) of an ASN GW. Upon receipt of a location information service request message from an LBS client, a location information server receives routing information for routing to an AA of an associated mobile station from the AAA server, and transmits a request for location information of the mobile station to the ASN GW. Upon receipt of the location information request from the location information server, a location information controller performs a location estimation procedure between the mobile station and an interconnected base station when the mobile station is in the idle mode, and upon receipt of location information from the base station, transmits the received location information to the location information server. | 10-30-2008 |
20080218936 | Analog capacitor - Analog capacitors, and methods of fabricating the same, include a lower electrode having a lower conductive layer, a capacitor dielectric layer on the lower conductive layer, and an upper electrode on the capacitor dielectric layer to be opposite to the lower electrode, wherein the upper electrode includes at least an upper conductive layer in contact with the capacitor dielectric layer, wherein the upper conductive layer has a resistivity higher than that of the lower conductive layer. | 09-11-2008 |
