How to Predict Fuel Cell Performance

The performance of a fuel cell stack can be estimated using a few equations combined with some input data. A common way of characterizing performance of different fuel cell stacks is using polarization curves. Although you cannot pinpoint specific issues with these curves, they will allow you to calculate the overall performance. An example polarization curve is...

Chemical Hydrides

Fuel cells often use compressed hydrogen as the fuel; however, many other hydrogen sources can be used with fuel cells. Chemical hydride storage is an alternative method of producing hydrogen via a chemical reaction. These reactions involve chemical hydrides, water, and alcohols. The chemical reactions are not reversible, and the byproducts must be discarded. Hydrogen fuel can also...
