Adapta-Stack

Disassemble and reassemble your own fuel cell stack of individually connected cells with the Adapta-Stack Hydrogen Air Proton Exchange Membrane (PEM) Fuel Cell. The Adapta-Stack is available in 1-cell, 5-cell, 10-cell, 15-cell, and 20-cell stack configurations, depending on your hydrogen power requirements. The ease of use makes it simple to scale to different power levels and integrate equipment such as sensors.

The Adapta-Stack is a fully assembled, tested, and ready-to-use PEM Fuel Cell. Only a Phillips head screwdriver and torque wrench (<50 in-lbs) are necessary to assemble/disassemble, so you can concentrate on creating your very own hydrogen-powered applications. Digital torque screwdriver or digital torque wrench sets (with 0 to 100 in-lbs capability) can also be used to assemble the Adapta-Stack hardware.

This kit is designed for educational purposes, allowing users to assemble and disassemble a single- or multi-cell PEM fuel cell to explore the principles of fuel cell technology. The Adapta-Stack Hydrogen Air Fuel Cell converts hydrogen and oxygen into electrical energy through an electrochemical reaction, producing water and heat as byproducts. The Adapta-Stack is intended for educational and demonstration purposes to teach the fundamentals of PEM fuel cell technology. It is suitable for students, educators, and researchers interested in renewable energy and hydrogen-based systems. The kit is not designed for commercial or industrial applications.

Hydrogen and atmospheric oxygen are required for operation of the Adapta-Stack Hydrogen Air Fuel Cell.

The Adapta-Stack Hydrogen Air PEM Fuel Cell is a dismantlable open-air cathode fuel cell that allows users to input their own custom PEM MEAs for testing!
