Part of the NATO Science for Peace and Security Series C: Environmental Security book series (NAPSC)

An autonomous device for the investigation and optimization of electrochemical energy converting cells (fuel cells, electrolyzer cells or bifunctional cells) and single electrodes operating with polymer electrolyte membranes and gaseous reactants and reaction products will be described. Two constructions using mini membrane electrode assemblies will be given offering a wide range of investigation opportunities for a deeper insight in the new high temperature gas phase electrochemistry of the system.

There were several beautiful lectures in this Institute where we learned that there is no single approach to fuel cells even if we restrict our selves to PEM Fuel Cells and hydrogen as fuel. Fuel cells range from watts to megawatts with enormous application possibilities, giving to the engineer a vast field of imagination for design and innovations.

Nevertheless there is one simple element which is common to all kinds of electrochemical energy converters (EcEC) including:
  • Fuel cells (FC) with chemical to electrical energy conversion,

  • Electrolyzers (ELZ) with electrical to chemical energy conversion,

  • Bi-functional EcEC (Bi-EcEC) with both ways on demand conversion, this element has got the name: The membrane electrode assembly or (MEA).

The MEA is the heart of an EcEC. It is the actual site of the electrochemical energy conversion. In a sense it is also a commercial end product. It is available on a square meter basis. If you would like to produce a fuel cell for your needs you buy the necessary amount of MEA, use your creative skills and make the envelope. It is not and easy and inexpensive task. The MEA may be even the cheapest item in your design. But the MEA dictates all. If you have a good MEA you may make a good EcEC.
