1-Cell Rebuildable PEM Fuel Cell Kit

H-TEC's 1-Cell Rebuildable PEM Fuel Cell Kit contains a Proton Exchange Membrane Fuel Cell (PEMFC) that can be completely disassembled and then reassembled, specifically for education and research purposes. The PEM fuel cell can run in Hydrogen/oxygen or hydrogen/air operation modes. All the tools needed for assembly are included!

In a fuel cell, chemical energy is converted directly into electrical energy, i.e., without the use of a combustion process. Hydrogen and oxygen (or ambient air) supplied from outside the process react electrochemically to form water, generating electrical current and heat in the process. The oxygen can be supplied in pure form or in the form of ambient air.

The membrane-electrode unit forms the heart of the PEM fuel cell. The following reactions take place within it:

• Cathode:4e^- + 4H⁺+O₂ →2H₂O
• Anode:2H₂ →4H⁺+4e^-
• Complete Reaction:2H₂+O₂ →2H₂O

Technical Specifications:

• Power in Hydrogen and Oxygen Mode: 1 W
• Power in Hydrogen and Air Mode: 800 mW (with Oxygen Plate)
• Power in Hydrogen and Air Mode: 1.2 W (with Air Plate; higher than oxygen mode due to better water and heat management)
• Electrode Area: 16 cm²
• Generated Voltage: 0.4 - 0.96 V DC
• Dimensions (H x W x D): 3.9" x 3.14" x 3.07" (98 x 80 x 78 mm)
• Weight: 8 oz (225 g)
