Using Micro-Transport Phenomena in MEMs Fuel Cells

A lot of work has been devoted to the development of long-lasting, efficient and portable, power sources for further technology improvements in commercial electronics devices, medical diagnostic equipment, mobile communication and military applications. These systems all require...

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...

Introduction to Electrolyzers

Electrolyzers use electricity to break water into hydrogen and oxygen. The electrolysis of water occurs through an electrochemical reaction that does not require external components or moving parts. It is very reliable and can produce ultra-pure hydrogen (> 99.999%) in a non-polluting manner when...

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...
