Build your own PEM hydrogen fuel cell from the endplates up!  The Flex-Stak fuel cell kit gives you all the materials you need to make your very own fuel cell from scratch.  It allows the user to increase their basic fundamental understanding of the fuel cell and all of the  components required.

The Flex-Stak Kit comes in a 1-cell, 5-cell, 10-cell, 15-cell, or 20-cell stack configuration depending on your hydrogen power requirements.  This open-air cathode stack can be fitted with various sizes of graphite plates, membrane electrode assemblies (MEA) and low temperature PEM membranes to run on Hydrogen and Air or Hydrogen and Oxygen.  The ease of use makes it simple to scale the Flex-Stak to different power levels and integrate equipment such as sensors.  The Flex-Stak fuel cell is an excellent learning tool that gives hands-on experience with promising fuel cell technology.  Whether it’s advanced research on MEAs, creating your own fuel cell lab or conducting professional training the Flex-Stak has a load of practical applications.

The Flex-Stak Assembled is a fully assembled, tested, and ready for use PEM Fuel Cell!  Only a flathead screwdriver and torque wrench (<50 in-lb, 1/4 inch nut) are necessary to assemble the Flex-Stak so you can concentrate on creating your very own hydrogen powered applications.

The Flex-Stak design is a dismantable fuel cell that allows for the user to input their own custom PEM MEAs for testing!

• Recommended Torque Value: 8-10 inlbs

 Flex-Stak Properties 1 Cell 5 Cell 10 Cell 15 Cell 20 Cell
 Nominal Output - Watts* 0.25 to 0.35 3 to 3.5 6 to 7 9 to 11.5 12 to 14
 Nominal Operating Voltage** 0.45 to 0.6 2.3 to 3 4.6 to 6 7 to 9 9.5 to 12
 Hydrogen Consumption (cc/minute) 10.6 53 106 162 400

* The provided power output numbers are based on the forced air operation using the fan.
** The Flex-Stak nominal operating voltage per cell is typically around 0.45 to 0.6 V, but could vary between 0.4 and 0.9V per cell depending on how hard you are running the cell (i.e. pulling more current will result in a lower cell voltage, less current will have a higher cell voltage).  Humidity of the H2 gas and stack temperature will also play a major role in the power output (or voltage or current) values.
