The increasing energy demand along with the growing attention on environmental issues require a change in the process of energy conversion, that can be accomplished through the exploitation of renewable sources and the development of new, sustainable and efficient technologies. Among renewable energy sources, biomass presents some positive characteristics: it is cheap, widely spread and can be exploited at any time. Moreover, if used at the same rate as it grows, biomass can be considered as not contributing to CO2 emission in the atmosphere. Thanks to the exploitation of the fuel cell technology, it is possible to convert the chemical energy contained in the fuel directly into electrical energy.
