The HA Series of TekStak Kits contains everything you need to quickly build a fuel cell stack and produce electricity from air and a low pressure hydrogen source. This series of kits is suitable for a wide range of uses, from quick classroom demonstrations for educators to powering RC cars for hobbyists. The HA products are designed around an “open cathode” or “air breathing” design that draws oxygen directly from the ambient air. Use a simple DC fan to increase the power output from your stack.

 

Each kit includes instructional materials to get you started. A DVD that demonstrates the proper construction of the stack and explains how fuel cells work is included along with an easy to read manual with more detailed information. The kits can be easily assembled, used, and then disassembled for easy storage when not in use. 

 

Kits are available in three sizes—1 cell, 5 cell, and 10 cell. In addition to the instructional materials described above, each kit includes

Molded Plastic Endplates

Parker TrueSeal® Fittings to hook up flow lines

Graphite Composite Bipolar Plates

5 mil Membrane-Electrode Assemblies (MEAs)

PTFE Gaskets

Nickel Plated Current Collector Plates

Assembly Hardware

The TekStak is a Proton Exchange Membrane (or PEM) fuel cell. PEM fuel cells work by converting hydrogen and oxygen from the air into water. This chemical reaction releases energy in the forms of heat and DC electricity. If you connect a load to the stack, such as a small fan or LED lamp, the electricity will flow powering the fan or lamp.
