Discloses is a porous separator for a fuel cell. The porous separator includes a flow plate and a flat plate. The flow plate includes a first flow surface upwardly inclined and having a first plurality of flow apertures and a second flow surface downwardly inclined and having a second plurality of flow apertures that are repeatedly arranged along a longitudinal direction of the flow plate. The flow plate is disposed between a gas diffusion layer of a fuel cell and a flat plate to seal the flow plate and create a flow path for hydrogen or air therein.

The disclosure relates to a system for controlling devices and information on a network by hand gestures, and more particularly, to a system for controlling devices and information on a network by hand gestures in which a device or a file to be controlled is selected by a user and a display device is pointed so that information and data can be shared and that various devices can be coupled to each other easily and can be controlled easily.The system for controlling devices and information on a network by hand gestures can remarkably improve the interaction between various input and display devices and a user under a ubiquitous computing environment.

A blower housing of a hydrogen recirculation device for a fuel cell vehicle includes a plurality of cooling pins installed on a perimeter of a housing body installed in a fuel processing system of the recirculation device. The cooling pins are arranged in parallel with air flow, thereby reducing a temperature deviation and the highest temperature point.

A separator for a fuel cell includes a flow field plate and a main body plate. The flow field plate has a porous plate structure and is bonded to an outer surface of a gas diffusion layer to form a reaction gas flow field. The main body plate is bonded to an outer surface of the flow field plate to seal the reaction gas flow field. The flow field plate has protrusions that protrude from both surfaces of the flow field plate in a repetitive pattern, forming an uneven structure. The flow filed plate has a land portion bonded to the gas diffusion layer at a sharp tip of a protrusion thereof protruding from one surface of the flow field plate and a bonding portion bonded to the main body plate at an opposite sharp tip of a protrusion thereof protruding from the other surface of the flow field plate.

An apparatus and method summarize a user's daily life information. The apparatus includes an information collection unit, an analysis unit, a story generator, and a display unit. The information collection unit collects log information including user's daily life information, from at least one electronic device. The analysis unit analyzes the log information collected from the information collection unit and decides at least one topic representing the user's daily life information. The story generator generates at least one sentence representing the user's daily life information using the at least one topic decided in the analysis unit. The display unit displays the at least one sentence generated in the story generator.

摘要:
A method for determining traffic conditions comprises: collecting real-time traffic information of a road; calculating a representative speed value for the road by a fuzzy inference, from the collected real-time traffic information and traffic condition factors having an effect on the road; and transmitting the representative speed value to a terminal of a vehicle traveling on the road corresponding to the representative speed value. The representative speed is sensibly determined and reliable information is supplied because the fuzzy inference's performance is based on the information collected from the signal transmitter and based on the factors which can affect the traffic conditions.
