Patent application numberDescriptionPublished
20090005237Method for preparing the mixed electrode catalyst materials for a PEM fuel cell - The present invention relates to a process for preparing electrode catalyst materials for a polymer electrolyte membrane fuel cell (PEMFC), and particularly to a high-performance platinum-non-platinum mixed electrode catalyst (Pt—RuOs/C) having a physically mixed structure of RuOs alloy and platinum materials, which is prepared by adding a small amount of platinum (Pt) to RuOs alloy materials highly dispersed on a carbon support, where the amount of platinum used is drastically reduced as compared to the conventional platinum materials, thus lowering the manufacturing cost.01-01-2009
20090155635METHOD OF ACTIVATING MEMBRANE ELECTRODE ASSEMBLY (PEM) OF POLYMER ELECTROLYTE MEMBRANE FUEL CELL (PEMFC) USING CYCLIC VOLTAMMETRY (CV) - The present invention relates to a method of activating membrane electrode assemblies of polymer electrolyte membrane fuel cells of a fuel cell stack for a vehicle comprising: supplying a humidified gas to a fuel cell so as to hydrate an electrolyte membrane and an electrolyte of electrodes of the fuel cell; and performing a cyclic voltammetry process so as to activate the layers of the electrodes.06-18-2009

Patent application numberDescriptionPublished
20100131562METHOD OF DYNAMICALLY MANAGING AND SHARING DATABASES IN A MOBILE COMMUNICATION TERMINAL AND A MOBILE COMMUNICATION SERVER SYSTEM - A method of dynamically managing and sharing database in a mobile communication terminal and a server system is provided. By installing applications such as a database system and a user interface programs in the mobile communication terminal, a user forms a database arbitrarily in a form of his/her own preference, input data there, and forms a user interface in a form of their preference. Also, the data managed in the mobile communication terminal may be stored and managed in a mobile communication server system through a wireless network or in a computer through a wired network. The user can download database template a provider provides to the mobile communication terminal from the mobile communication server, use them without generating the database structure for him/herself, and graphs and numerical expressions the user produced using the data of database may be included. Also, the template may be set with sharing right and using right, such that the user can use the template only within the allowed scope of sharing and using.05-27-2010
