Fuel Cell Interface from LearnOnLine.com

The Fuel Cell Interface will allow you to completely characterize the performance of a reversible PEM fuel cell.  This high precision instrument comes equipped with a 12-bit A/D converter for highly accurate current and voltage measurements with loads down to 0.1 ohm. With your solar panel or other voltage source connected, you can plot and log input and output voltage, current and power in real time.

Simply push and hold the red button to begin charging the fuel cell, and witness the characteristic charge cycle as shown below on the left.  After releasing the red button the fuel cell will begin its discharge cycle (center of plot), the rate of which is dependent on the applied. load. 

All relevant materials are supplied including a 6' RS-232 to USB serial cable, StampPlot graphical software (above) and a User Manual on CD-ROM.  9-volt battery, fuel cell and external power source not included.

Students can create plots of the fuel cell and solar data like that above.  These plots can be saved as graphic files for inclusion into student reports or be printed out to take home to show parents.  This plotting software also has the capability to log data for inclusion into spreadsheets.
