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...

Different characterization techniques enable the quantitative comparison of every property and part of the fuel cell stack. By characterizing the fuel cell properly, you can understand why the fuel cell is performing well or poorly. These techniques help discriminate between activation, ohmic and concentration losses, fuel crossover, and...

The first Columbia Chemical Engineering Fuel Cell Car Demonstration and Competition was planned, developed, and executed in order to inspire and educate young people about chemical engineering. This hands-on experience was modelled after the American Institute of Chemical Engineers (AIChE) ChemE Car Competition using the X7 Fuel Cell Car....
