The aim of this chapter was to summarize the techniques used for surface modification of BDD materials, improving their catalytic efficiency as supported catalysts for PEM fuel cells (methanol and ethanol oxidation) as well as the studies concerning to the production of electrochemical capacitors using BDD materials. Also, the recent advances on the use of modified BDD materials for fuel cells will be discussed.
IntroductionPetroleum is considered the main source of energy, but it has also caused considerable amount of damages such as atmospheric pollution and global warming. Nevertheless, the copious uses of petroleum as well as the demand of petrol in the near future have motivated scientists around the world to develop new clean and renewable energy sources. In this frame, the development of fuel technology has received great attention because this technology consists in directly converting
