| Abstract |
|
Composite materials are a new class of materials that combine two or more separate components into a form suitable for structural applications. While each component retains its identity, the new composite material displays macroscopic properties superior to its parent constituents, particularly in terms of mechanical properties and economic value. Perhaps best known for their use in aerospace applications, advanced composites are also used by the automotive, biomedical, and sporting goods markets. In addition, these strong, stiff, lightweight materials are seeing increased use in the rehabilitation, repair, and retrofit of civil infrastructure, including, for example, as replacement bridge decks and wrapping for concrete columns. New composite materials presenting some interesting features which are not directly related to their mechanical properties are appearing. This is the case of noble metal-based polymeric composites, the preparation and characterization of which are considered in this article with regard to their electrochemical properties. These composites are of great practical interest because of potential applications in water electrolysis and H2-O2 fuel cells. Electrolyzers and fuel cells can be used for terrestrial transportation, oxygen generation in submarines, and energy conversion in spacecraft.
