| 20110094897 | Hydrogen Storage Device - A hydrogen storage device includes a first casing and a second casing. A hydrogen storage material is disposed in a receiving space formed inside the first casing. The second casing encloses the first casing such that the first and second casings jointly form an outer flow channel structure. Furthermore, the first casing has a surface extended inward of the first casing to form a recess. By disposing a baffle inside the recess, a curved inner flow channel structure is formed in the recess of the first casing. With this simple structure, a heat exchange substance can exchange heat with the hydrogen storage material, which is disposed inside the receiving space, via both the outer flow channel structure and the curved inner flow channel structure. Therefore, the heat exchange rate can be increased to accelerate the storage and release of hydrogen. | 04-28-2011 |
| 20110156665 | LINEAR MODULATION VOLTAGE TRANSFORMER CIRCUITRY - A linear modulation voltage transformer circuitry includes a power stage unit, a voltage division unit, a linear modulation unit, an error amplifier, and a recursive controller. The power stage unit adapts an input voltage and outputs a first voltage to the voltage division unit, which outputs a divided voltage. The linear modulation unit receives the divided voltage, compares it with a control voltage, and outputs an error voltage signal to the error amplifier, which amplifies the error voltage signal as an error gain control signal. The recursive controller receives and modulates the error gain control signal and outputs the modulation error gain control signal to the power stage unit as a reference signal so as for the power stage unit to modulate the first voltage. Thus, the first voltage can be varied in real time via the linear modulation unit to meet load demands. | 06-30-2011 |
| 20110160928 | RANDOM CONTROLLED FUEL CELL POWER MODULE - The present invention discloses a random controlled fuel cell power module. The random controlled fuel cell power module includes a power module system, a current detection unit, and a random control unit. The power module system is composed of at least two parallel-connected DC/DC converters, for providing the power for a load. The current detection unit detects a load current value of the load. The random control unit reads the load current value and randomly assigns a control mode to activate the DC/DC converters according to the load current value, so that the DC/DC converters can be equally used. Therefore, the failure rate of the DC/DC converters is reduced, the life of the power module system is relatively prolonged, and the stability of the power module system is simultaneously increased. | 06-30-2011 |

| 20090320056 | SYSTEM OF USING SET-TOP BOX TO OBTAIN AD INFORMATION - A system of using a set-top box to obtain ad information includes a remote control, a set-top box, a program system server, and an advertising server. A first ad request corresponding to a target ad is transmitted to the set-top box via the remote control so as to obtain ad information of the target ad. A second ad request corresponding to the first ad request received is produced and transmitted to the program system server by the set-top box. A third ad request corresponding to the second ad request received is produced and transmitted to the advertising server by the program system server. The advertising server obtains a user's contact information and the ad information of the target ad according to the third ad request and transmits the ad information to the user. Hence, the user obtains the ad information of the target ad conveniently by the set-top box. | 12-24-2009 |
| 20100179816 | Digital Lifetime Record and Display System - A digital lifetime record and display system is provided. The digital lifetime record and display system includes a data input module, a database and a lifetime display module. Time and corresponding image related data are inputted through the data input module and respectively saved as the time related data and image paths in the database. Additionally, the lifetime display module has a timeline unit which displays time points corresponding to the time related data and a time display unit and an image display unit which both correspond to the time points. Thus, the lifetime display module can display time related data and a representative image which is one of the corresponding image related data. The digital lifetime record and display system can build up a personal image timeline for memorizing or sharing. | 07-15-2010 |
| 20100196775 | Heat Recycling System of Fuel Cells - A heat recycling system of fuel cells is provided. The heat recycling system includes: a fuel cell apparatus, a cooling tank, an adsorption refrigerating apparatus, a first set of valve, and a second set of valve. The adsorption refrigerating apparatus has a first adsorption bed, a second adsorption bed, a first evaporator/condenser, and a second evaporator/condenser. The first set of valve connects the fuel cell apparatus and the cooling tank to the first adsorption bed and the second adsorption bed. The second set of valve connects the first evaporator/condenser and the second evaporator/condenser to the cooling tank. Switching of the first and the second sets of valve is controlled by an automatic control system communicating between the fuel cell apparatus, the cooling tank, and the adsorption refrigerating apparatus. Thus, waste heat generated by the fuel cell apparatus is timely brought away, recycled, and reused by the adsorption refrigerating apparatus. | 08-05-2010 |
| 20100255391 | FUEL CELL STRUCTURE HAVING COMBINED POLAR PLATES AND THE COMBINED POLAR PLATES THEREOF - A fuel cell structure having combined polar plates and the combined polar plate thereof are disclosed. The fuel cell structure includes a membrane electrode assembly, the combined polar plate, and a charge collection plate. The combined polar plate and the charge collection plate are arranged on outer surfaces of the membrane electrode assembly. The combined polar plate includes a non-porous plate and a porous plate. The non-porous plate has a base plate and a frame which together define a recess. A portion of the base plate free of the frame has at least one flow channel. The porous plate is received in the recess and sandwiched between the membrane electrode assembly and the base plate. Pores of the porous plate increase flow rate of fuel, and the flow channel drains water, a product of electrochemical reaction, from the fuel cell structure quickly to enhance performance of power generation. | 10-07-2010 |
| 20100310962 | FUEL CELL STACK WITH TRANSPARENT FLOW PATHWAYS AND BIPOLAR PLATES THEREOF - A fuel cell stack with transparent flow pathways and bipolar plates thereof are provided. The fuel cell stack includes at least one membrane electrode assembly (MEA) and at least one pair of bipolar plates. Each bipolar plate includes a transparent flowing path plate and a current collector. Each MEA is interposed between two corresponding bipolar plates so that power generated by each MEA is transmitted through the current collectors disposed respectively on margins of adjacent ones of the transparent flowing path plates. The transparent flowing path plates allow the production of liquid water in the fuel cell stack to be monitored in real time from outside the fuel cell stack, so as to prevent flow pathways of the transparent flowing path plates from being blocked and thereby maintain the efficiency of power generation of the fuel cell stack. | 12-09-2010 |
