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...

Techniques for Measuring Fuel Cell Resistance

The fuel cell polarization curve provides useful information on fuel cell performance, however; additional information is needed to study its performance characteristics accurately. Cell resistance provides insightful information about a fuel cell that is not completely captured by polarization curves. Since fuel cell current densities are high in comparison with...

Polarization Curves

If you work with fuel cells, then you are definitely working with polarization curves. The polarization curve does not have a lot of specificity; however, it is one of the most common methods of testing a fuel cell. It also allows an easy comparison to other published polarization curves. The polarization curve displays the voltage output of the fuel cell for a given current density loading...
