How to Estimate Electricity Requirements

When you receive your energy bill each month, you may not understand exactly how the total amount has been calculated. Every device or appliance in your household contributes to the total sum of the bill. To figure out which appliances and devices are using the most energy, you can estimate the...

Power Electronics for Renewable Energy Systems

Hybrid renewable energy power systems are positioned to become the long-term power solution for portable, transportation and stationary system applications. Hybrid power systems are virtually limitless in possible setups and configurations to produce the desired power for a particular system. A hybrid system can consist of...

Transport of Electrons through the Fuel Cell

If you look at any basic fuel cell diagram, you can see that the fuel cell generates electrons. In the scientific or engineering circles, these electrons have many names, but a common term is “charge transport.” Charge transport is the movement of charges from the electrode (where they are produced) to the...

The Fuel Cell Electrolyte Layer for Low-Temperature Fuel Cells

The electrolyte layer is essential for a fuel cell to work properly. In low-temperature fuel cells, when the fuel in the fuel cell travels to the catalyst layer, the fuel molecule gets broken into protons (H+) and electrons. The electrons travel to the external circuit to power the load, and the hydrogen proton (ions) travel through the electrolyte until it reaches...
