  • Page 3: Introduction

    All steps required for setup, operation and assembly/dismantling of the PEMFC Kit are described below. Please read through the Operating Instructions carefully beforehand. H-TEC Education wishes you many enjoyable hours learning about this technology with the PEMFC Kit. www.myhtec.com...

  • Page 4: Intended Use

    Intended Use The PEMFC Kit allows the principle of proton exchange membrane (PEM) fuel cells and PEM electrolyzers to be demonstrated and measurements taken. The system has been developed for teaching and demonstration purposes only. Any other use is prohibited! Hydrogen and oxygen are required for operation of the PEMFC Kit.

  • Page 5: General Safety Precautions

    General Safety Precautions • The system is intended for teaching • The system is not a toy. Operate the and demonstration purposes in schools, PEMFC Kit and keep it and the gases universities, institutions and companies produced out of the reach of small only.
  • Page 6 • Tell you students about any potential dangers and carefully supervise experimentation. H-TEC Education does not accept responsibility for injuries or damage sustained in the event of these Safety Precautions not being followed. www.myhtec.com...

  • Page 8: Operation Of A Pem Fuel Cell

    Operation of PEM fuel cell In a fuel cell, chemical energy is converted directly into electrical energy (i.e. without use of combustion process). Hydrogen and oxygen supplied from outside the process react to form water, generating electrical current and heat in the process. The oxygen can be supplied in pure form, or in the form of air.
  • Page 9 Important! Important! An oxygen supply is not essential for use of the H-TEC Education PEMFC Kit. In the absence of an oxygen supply, the cell operates as an air-breathing fuel cell. It obtains sufficient oxygen from the atmosphere by diffusion and convection. In this operating mode, however, full power is not reached.
  • Page 10 “Closed outlet” gas supply mode “Closed outlet” gas supply mode The “closed outlet” gas supply mode is employed with all hydrogen sources which deliver the gas at a slight pressure (e.g. by means of a water column) and with which the hydrogen would thus escape unused in the “open outlet”...
  • Page 11 Assembly The PEMFC Kit can be completely dismantled. Note that the proton exchange membrane and the electrodes are extremely sensitive components. They can be removed from the cell and shown to students. However, we strongly advise against passing these components around the class. Disassembly 1.
  • Page 12 Assembly Assembly of the cell is the reverse of the dismantling. If reassembling with the air plate, Step 1 should be done with air plate instead of hydrogen plate. Always wear gloves when handling the membrane. 1. Place a washer over each of the four bolts. Insert the bolts into one of the housing plate and turn it upside down so it is resting on the head of the bolts.
  • Page 13 Assembly 3. Holding the membrane electrode assembly (MEA) at two opposite corners, place it upon the perforated plate. 4. Place the second (negative) perforated plate in position. The thicker side of the seal must face towards the acrylic housing which is not yet in place.

    Assembly 5. Place the acrylic housing on the screws. 6. Place the remaining washers and nuts on the screws, and screw the nuts finger-tight at first. 7. Tighten the nuts alternately a little at a time (max. two and one-half turns) until a gap of 4mm is left between the acrylic plates.

  • Page 15: Troubleshooting

    Negative Voltage Never connect an external voltage to the fuel cell, as this will instantly destroy the catalyzer. Maintenance The H-TEC Education PEMFC Kit is maintenance-free. Disposal Do not dispose of fuel cells and electrolyzers as general household waste. According to European regulations, used electric and electronic devices may no longer be disposed of as unsorted household waste.
