Introduction: After more than 20 years of experience in EV applications, the sodium nickel chloride technology is fully mature for large scale energy storage. Early on, mathematical modeling of Na-MCl2 cell (M standing for Fe or Ni) has attracted attention to help identifying predominant mechanisms at work during operation. However, these models were rarely validated with data coming from ...

The purpose of this study is to understand the growth mechanism of copper (Cu) films on a Cu-Zn system substrate with a pre-defined pattern. The pattern was defined by conducting a selective etching process on a two-phase polycrystalline substrate. As a result of this process, there were etched regions correspondent to beta-phase crystals and quasi non-etched regions that belong to alpha-phase ...

PEM fuel cells are very promising for portable applications. A key component of fuel cell is the flow field plate through which hydrogen will reach the anode, oxygen will reach the cathode and electron collection. Flow field plate made of silicon is not a good electrical conductor , so electrical contacts has to be attached to the Gas Diffusion Layer (GDL) for taking the power to outside ...

The reciprocating paddle cell is a known practical method for depositing alloy films on wafer substrates. Recently, the mass transfer boundary layer within an industrial wafer plating cell was studied based on the measurement of limiting current. It was indicated that a shear-plate fluid agitation mechanism is capable of generating a thin (i.e.

The microband design of microelectrodes is a cost-effective and easily-fabricated compromise combining convergent mass transport, due to microscale width as a critical dimension, and high output currents due to the macroscopic length. Among the various techniques available for microband electrode fabrication, screen-printing stands out as an inexpensive approach. The application of cross cutting ...

Fuel cells are devices that convert chemical energy of a fuel into electrical energy through electrochemical processes. One of the types of fuel cell is the Solid Oxide Fuel Cell (SOFC) that uses solid ceramics for electrolytes. Numerical simulation involves constructing a mathematical model of the SOFC and use of specifically designed software programs that allows the user to manipulate the ...

For the successful exploitation of microdevices such as microsensors, development of micro-power sources is strongly required. In this view, microbatteries and microfuel cells have been developed. Here the concept of on-chip fuel cells, which consist of all the components necessary for power generation integrated on a chip, is introduced. Then, in order to improve their performance, experimental ...

Rechargeable batteries solve electrification and communication problems. As examples, hybrid battery-diesel generator power supplies efficiently power cell towers in remote locations, detached from the power grid. Large battery banks are used to load level user power requirements, reducing stress on power generation infrastructure. Batteries firm the output capacity of intermittent wind ...

Failure of conventional lead-acid battery is attributed to degradation of solid active mass (PbO2 and PbSO4 ). A number of research efforts are underway worldwide to overcome degradation of active mass to improve the cycle life of lead-acid batteries. Soluble lead-acid flow battery (SLFB) is a new kind of lead-acid flow battery in which products of discharge remain in dissolved state. SLFB ...
