Abstract: Disclosed is a fuel composition for fuel cells with improved performance. In order to efficiently remove undesirable intermediates of a fuel cell that uses liquid oxygenated hydrocarbons as fuel thereof, polyoxometalate as an oxidation assistant is directly added to the fuel cell. Herein, polyoxometalate includes at least one redox reactive anion caused by dissolution of polyoxometalate in an organic medium containing solution and/or an aqueous solution. The intermediates generated during activating the fuel cell are efficiently oxidized and, additionally, carbon monoxide with the property of catalyst poisoning of electrode catalyst is eliminated, thereby accomplishing improvements in poisoning resistance of the catalyst and, in turn, performance of the fuel cell.

Abstract: A media processing device uses an external storage device. The media processing device includes a storage device access module, an information source, a program memory, a system memory, a signal processor, a user interface and a system controller. The system controller accesses the external storage device, reads file information, and constructs contents to be displayed. When the system controller receives a command to select a media file, the system controller accesses the external storage device, searches for the selected media file, reads data of the searched media file, copies the read data, and provides the copied data to be decoded. When the system controller receives a commend to encode a signal, the system controller controls the signal processor to encode the input signal into media data, constructs a media file from the encoded media data, positions the media file, and copies the constructed media file when the external storage device is accessible through the storage device access module.

Abstract: Disclosed herein is a media processing device using an external storage device. The media processing device includes a storage device access module, an information sourcing module, a program memory module, a system memory module, a signal processing module, a user interface module and a system control module. The system control module accesses the external storage device, reads file information, and constructs contents to be displayed. When the system control module receives a commend to select a media file, the system control module accesses the external storage device, searches for the selected media file, reads data of the searched media file, copies the read data, and provides the copied data to be decoded.
