This is a general purpose, build-it-yourself1 hydrogen/air fuel cell kit that allows you to build the fuel cell from the endplates up. Building the fuel cell from scratch allows the user to increase their overall understanding of the fuel cell and its components.


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

Kit Contents Include:

✔ Plastic Endplates
Graphite Composite Bipolar/Monopolar Plates
✔ High Performance PEM MEAs
✔ Gasketing
✔ Expandable Design (See Flex-Stak Expansion Kits)
✔ Hardware
✔ Guide Dowels
✔ Dis-assembly and Reassembly Instructions

Please note that the kits do not come with the plastic case seen in the picture.

Technical Properties:

• MEA Active Area: 3.2 x 3.2cm (10cm²)
• MEA Membrane Area: 5.3 x 5.3cm
• Graphite Plate Overall Dimensions (L x W x D): 6.3 x 6.3 x 0.4 cm
• 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.
