Abstract: Disclosed are an apparatus and method enabling a user to efficiently share contents. A user of an electronic device performs an image capturing by use of a camera, thereby generating an image capture event. According to the image capture event, the electronic device obtains address information of a content transferring apparatus and transfers a content requesting message to the content transferring apparatus having the address information. Upon reception of the content requesting message, the content transferring apparatus provides the electronic device with contents in execution and status information of the content. The electronic device uses the content and the status information to restore a status of the content which has been executed in the content transferring apparatus.

Abstract: An evaporative humidifier for a polymer electrolyte membrane fuel cell system including a fuel cell stack, comprising: a condensation channel to which exhaust gas from the fuel cell stack is introduced; an evaporation channel to which supply gas for the fuel cell stack is introduced; a partition wall for separating the condensation channel and the evaporation channel from each other; and a water distribution unit for supplying water into the evaporation channel, wherein the water is condensed in the condensation channel by heat exchange between the exhaust gas and the supply gas.

Abstract: A heat exchanger having an extended surface plate includes a plurality of heat exchanging bodies having therein flow paths along which a heat transfer medium flows, and extended surface plates each disposed between the heat exchanging bodies and having inclined surfaces in horizontal and vertical directions. Also disclosed is a dehumidifier having the heat exchanger. Moisture in the air may be effectively absorbed by a dehumidifying liquid, and the heat exchanger may have enhanced structural strength.

Abstract: Disclosed is a fuel cell including, a stack having fuel channels through which fuel flows and air channels through which air flows, the fuel channels and air channels being located at both sides of a reaction film, an actuator disposed to be involved in the air channels, the actuator allowing external air of the stack to affect the air channels, and a skirt extending from the stack with communicating with the air channels.
