Abstract: A draining device for use with a fuel cell system includes a recovery tank, a water-absorbing article and a blower. The fuel cell system performs an electrochemical reaction to produce water and heat. The recovery tank is in communication with the fuel cell system and includes a plurality of openings and a receptacle for accommodating the water. The water-absorbing article is disposed within the receptacle of the recovery tank for absorbing and dispersing the water. The blower is in communication with the recovery tank for introducing ambient air into the recovery tank. The water is vaporized into steam by the heat produced from the electrochemical reaction of the fuel cell system. The ambient air introduced by the blower forces the steam to discharge to the surroundings via the openings of the recovery tank.

Abstract: A planar fuel cell assembly includes a plurality of fuel cell units and a first channel-forming plate. The plurality of fuel cell units are connected in series. Each fuel cell unit includes a meshed metal plate and a membrane-electrolyte assembly. The membrane-electrolyte assembly of each fuel cell unit has a first side in contact with a second portion of the meshed metal plate and a second side in contact with a first portion of the meshed metal plate of an adjacent fuel cell unit. The first channel-forming plate cooperates with the plurality of fuel cell units to define a channel for flowing a fluid fuel therethrough.

Abstract: A fan is disclosed for use in a system, and the system has at least one connection structure. The fan is mainly composed of an impeller and a base, and the impeller is connected to the base. The impeller at least has a hub, a plurality of blades and a driver. The base has at least one engaging member, and the engaging member is corresponding to the connection structure. Further, the fan is fixed on the system by connecting the engaging member and the connection structure together.

Abstract: A movable mechanism for using with an electrical apparatus, in which the electrical apparatus has a casing having a receptacle for mounting therein the movable mechanism, to be dissipated by at least one heat-dissipating device installed in the movable mechanism. The movable mechanism includes a housing pivotally connected to the electrical apparatus in receptacle and having a slit for replaceably inserting therein the at least one heat-dissipating device.

Abstract: A composite heat sink with high density fins and a method for assembling the composite heat sink are disclosed. The composite heat sink includes a base and a plurality of fins detachably connected to each other, wherein each fin includes a plate and a bottom perpendicularly extended from a first end of the plate. Furthermore, each bottom of the fin is disposed on a surface of the base.
