Sustentabilidade: A tecnologia do Hidrogênio na geração de energia elétrica.

Currently the society has been increasingly concerned with environmental problems caused by its own unsustainable development. With technological advances, also came the machines, factories, automobiles, and with all this, the desire to move more and more. This theme reminds us to focus the technology develo pment of fuel cells (FC), a system of power generation with low emissions associated with a high efficiency, compared to the combustion engine, for example. The need to move in generation and distribution has be come a worldwide trend and studies aimed at the improvement in energy production can encourage sustainable system. The technology of fuel cells (CACs) is presented in this article as an instrument of adaptation to our needs and demands, contributing to the use of cleaner and renewable resources, such as hydrogen.
