Suppose, however, one reversed the emphasis and made a second fuel cell principle concerning spontaneous electrosynthesis. Then one would concentrate, not on the energy produced (now the by-product), but on the substance. Obviously, one would have to choose a situation in which the spontaneously acting overall reaction in the fuel cell produced a worthwhile product. To take a very simple example, suppose one led Cl2 gas, instead of 02 to the cathode of a fuel cell and ethylene instead of hydrogen to the anode. At the cathode one would find ... 

Fig. 13.35. A speculative schematic of a possible future application of the second fuel cell principle.

It is suggested in this book that there is a second fuel cell principle. The first one is concerned with the highly efficient conversion of chemical fuels to electrical energy. The second is concerned with direct electrochemical production of materials without the use of outside electricity. In fact, the method would produce electricity as a by-product that can be transmitted to places far away. 

Consider a manufacturing community of 100,000 persons, the levelized total energy consumption of which (including industry and military) is lOkW/person. Further, assume that one-quarter of these persons are employed in the synthesis of chemicals, using the second fuel cell principle (Section ). As a simplification, assume the manufacture is carried out by fuel cells working at 0.6 V and a current density of 1 A cm-2. The manufactured item has a molecular weight of 300 and requires 8 e0 per mole in its synthesis.

It is our expectation that this book will provide updated information on the direct alcohol fuel cell principles, materials, and performance for students, electrochemists, chemical engineers, and material scientists, as well as public interested in cleaner energy sources.

CEMs such as Nation remain state-of-the-art H" ion conductors in fuel cells to this day. However, much research is being done to improve CEMs in PEMFC and DMFC. AEMs as OH ion conductors are also being investigated for alkaline hydrogen and alcohol fuel cells (see entry Fuel Cells, Principles and Thermodynamics ). Such new membranes will likely be suitable for SPE electrosynthesis in the future.
