RESUMO

The current global energy situation shows the dependence on the electric energy, and the importance of the rational use of energy and the reduction of pollutants in the production of energy. The hydrogen as source of generation of electrical energy in fuel cells uses an abundant resource in Earth, and produces electrical energy with no pollution. The fuel cell consists of an electrochemical converter, that converts the chemical energy from the hydrogen and oxygen reagents into electric energy (continuous current), water and heat. This technology is promising and presents a range of applications in every day life, being attractive in relation to the other conventional technologies, due to increments in the efficiency, emission of pollutants, simplicity, longer life and smaller weight, being modular and silent. The cells the fuel have applications in the automotive segment, as auxiliary generation in electrical installations, generation of energy for portable equipment and space programs. Among the restrictions there is the cost of the cell and the hydrogen production and how to store it. The hydrogen is not a primary source of energy, but can be obtained from processes such as fossil electrolysis, plasma pyrolysis, bio fuels as the urban garbage and the biomass. This paper presents a study of the state of the art of this technique and also a systematization of the ways in which it can be used as auxiliary generation in automated electric installations. This technology, of recent development, has its interest increased by the environmental restrictions to the sources of energy and also by the cost reduction that is forecast. There is also a case study with a comparison between fuel cells and other more conventional options as the diesel generation. The paper is carried out for an existing computer processing center in an educational institution.
