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 ... Read more

As fuel cell size decreases, the transport phenomena of the fuels and water changes in the fuel cell. In standard fuel cell designs, the movement of f... Read more

Fuel cells with polymer electrolyte membranes are appealing because of their low-temperature operation and relatively simple construction. The polymer... Read more

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 electr... Read more

Most people wouldn’t think that much thought needs to be put into fuel cell components such as fuel cell gaskets, spacers, and end plates, however, ev... Read more

Each component of the fuel cell must be designed properly – otherwise, you run the risk of decreasing fuel cell performance. The bipolar plates are te... Read more

After you understand the basic concepts around designing, building, and testing fuel cells, the next step is optimization. Optimization often involves... Read more

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 varie... Read more

The fuel cell polarization curve provides useful information on fuel cell performance, however; additional information is needed to study its performa... Read more

Fuel cell operating conditions depend upon the cell and stack design. The operating parameters that affect fuel cell performance are: Operating Pressu... Read more

Fuel cell modeling is helpful for fuel cell developers because it can lead to fuel cell design improvements, as well as cheaper, better, and more effi... Read more
