  • Patent number: 11258263
    Abstract: An apparatus of solid oxide fuel cells (SOFC) is provided. The SOFCs generate power and are grid-tied. The apparatus comprises a power-generating side; and a grid-connecting side using an elementary household power management. The apparatus solves problems like low voltage, high current, voltage oscillation, voltage dips, long generator-starting time, etc. The apparatus is not only used as a stable power supply (base load), but also helps adjust the regional peak electricity demands. The features include the following: 1. A grid is tied, where output power does not pass through a direct-current boost converter and, thus, has no loss from it. 2. Injures, including voltage oscillation and sudden unloading after dumping, are reduced for avoiding further damages to cell sheets. 3. With the coordination of elementary power management and the integration of grid, the limitation of long-awaiting generator-starting time is crossed out and convenience of immediate power use is achieved.

  • Patent number: 9630166
    Abstract: A method is provided for fabricating a catalyst carrier. At first, aluminum hydroxide is used for forming an alumina powder. The alumina powder is mixed with carbon nanotubes and a complex additive to be shaped into a cake. The cake is kneaded into a noodle-like shape to be hot-dried. Then, calcination is processed in a furnace under 1200 celsius degrees (° C.) with air passed through. The crystal structure remains without phase change. A catalyst carrier of ?-alumina having nano-scaled pores is formed. The catalyst carrier is a powdery material made into different three-dimensional forms. The catalyst carrier thus fabricated is suitable for generating hydrogen through methane reformation. The catalyst carrier has a methane conversion greater than 99 percents. The catalyst carrier will not be crumbled under 800° C. for 4000 hours without carbon deposit.

  • Publication number: 20160375425
    Abstract: A method is provided for fabricating a carrier catalyst. The carrier catalyst uses an annular carrier of ?-alumina (?—Al2O3). The annular carrier of ?—Al2O3 has stable activity. By analyzing characteristics and methane conversion rates of catalysts with different compositions, a solution for solving carbon deposition is found. Cerium oxide (CeO2) is used as an accelerator and platinum (Pt) nano-particles are used as catalyzer. The above components are impregnated and coated on the annular carrier of ?—Al2O3. Thus, an annular-carrier catalyst of Pt/CBO2/?—Al2O3 is formed. Therein, the present invention uses carbon nanotubes before calcining the annular carrier catalyst. Consequently, its microstructure is modified to obtain a surface area of 130 square meters per gram and an average pore size of 12.585 angstroms. Preferably, 0.5 percents of platinum nano-particles are to be added into the carrier catalyst to achieve a 79% methane conversion rate even after 25 hours of reformation reaction.

  • Patent number: 8928328
    Abstract: A testing device for solid oxide fuel cell (SOFC) is disclosed. The testing device which combines the original cell housing with a four-point probe equipment is set for measuring SOFC MEA. The current collectors on anode and cathode in the original cell housing are respectively replaced by four independent probe units. They are not only to collect current but also to become measuring probes. Therefore, the lateral impedance of anode and cathode can be measured. Furthermore, the local characteristics are examined by open circuit voltage (OCV), I-V curve, and electrochemical impedance spectroscopy (EIS) measurements. The results show that the lateral impedance is substantially varied with temperatures. The distributions of OCV, current density, EIS and cell voltage in long-term test at the center of the cell are different from the edge.
