DMFC Adapta-Stack

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

The Adapta-Stack DMFC is a fully assembled, tested, and ready-to-use 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 methanol-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 DMFC to explore the principles of fuel cell technology. The Adapta-Stack DMFC converts methanol and oxygen into electrical energy through an electrochemical reaction, producing water, CO₂, and heat as byproducts. The Adapta-Stack DMFC is intended for educational and demonstration purposes to teach the fundamentals of fuel cell technology. It is suitable for students, educators, and researchers interested in renewable energy and methanol-based systems. The kit is not designed for commercial or industrial applications.

Methanol and atmospheric oxygen are required for operation of the Adapta-Stack DMFC.

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