Flex-Stak Assembled
Flex-Stak Assembled
The Flex-Stak is a fully assembled, tested, and ready-to-use PEM fuel cell! Only a flathead screwdriver (1/4 inch) and torque wrench (<50 in-lb, 1/4 inch nut) are needed to disassemble the Flex-Stak so you can focus on building your own hydrogen-powered applications. Digital torque screwdriver sets or digital torque wrenches (with 0 to 100 in-lbs capacity) can also be used to assemble the Flex-Stak hardware.
Description
Description
Disassemble and reassemble your own fuel cell stack of individually connected cells with the Flex-Stak Hydrogen Air PEM Fuel Cell. The Flex-Stak comes in a 1-cell, 5-cell, 10-cell, 15-cell, and 20-cell stack configuration depending on your hydrogen power requirements. 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 is a dismantable open-air cathode fuel cell that allows for users to input their own custom PEM MEAs for testing!
Stack Contents Include:
✔ Plastic Endplates
✔ Graphite Composite Bipolar/Monopolar Plates
✔ High Performance PEM MEAs
✔ Expandable Design (See Flex-Stak Expansion Kits)
✔ Hardware

| 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 output values provided are based on forced air operation.
**Flex-Stak nominal operating voltage per cell is typically around 0.45-0.6V, but could vary by 0.4-0.9V per cell depending on how hard the cell is being used (i.e. more current drawn will result in lower cell voltage, and less current drawn will result in higher cell voltage). H2 gas humidity and stack temperature will also play a role in output power (or voltage or current) values.
