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...
If you took the electrical output directly from a fuel cell, it would be an unideal power source. The output of a fuel cell is a DC voltage that varies widely and has a limited overload capacity. The electrical output is slow to respond to load changes because it is based on a chemical reaction, and may have...
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...
