Synthesis and Conducting Properties at Intermediate Temperature of BaCe1-xYxO3-α
It is well known that because high-temperature proton conductors have special proton-conducting function, they have valuable and potential applications in some electrochemical devices and membrane reactors such as fuel cells, gas sensors, hydrogenation and dehydrogenation of some organic compounds, ammonia synthesis at atmospheric pressure, steam electrolyzer, and separation and purification of hydrogen, etc.Y2O3 doped BaCeO3 [...]
Research on Active Power Filter in Reactive Power Compensation and Harmonic Restraining
With the development of the electronic technology and the extensive apply of the power electronic device,Higher requirements about using and quality of power are put forward.Active Power filter(APF) is considered as the most effetive method to harness the serious “power pollution”.It is a developmental tendency of utilizing APF compensating harmonic current and idle-current.In order to [...]
Preparation and Properties of Interconnect Materials for Solid Oxide Fuel Cells
Solid oxide fuel cells （SOFCs） are high efficiency and clean power system, which convert the chemical energy of the fuels directly to electrical energy. As an open circuit voltage of single cell at operation is approximately 1 V, the cells must be connected electrically in series with the help of an interconnect material to provide [...]
Experimental Study of Dynamic Per-Formance of Small Passive Direct Methanol Fuel Cells
Fuel cells are the devices which continually convert the chemical energy of the fuel and oxidant into electrical energy through the electrochemical reaction directly. Because of their environmental compatibility and high efficiency, fuel cells have drawn increasing attention from governments and enterprises all over the world. Direct methanol fuel cells (DMFCs) have the advantages of [...]
The Reliability Analysis of Microwave Anechoic Chamber and Its Automatic Test Systems
Recently, with the increasing application of wireless communication, the test techniques of the RF terminal equipments such as the mobile phone are paid more attentions, which mainly include the test of gain, TRP (Total Radiated Power) and TIS (Total Isotropic Sensitivity). These test processes should be in the microwave anechoic chamber. So the characteristics of [...]
