The is necessary to undertake actions aimed at

The 21st century has been marked by numerous
changes concerning the way we understand and use energy.  During the recent Paris Conference, it was decided unanimously to
considerably reduce the use of fossil fuels to reduce the emission. It will certainly have a major
impact on the future energy strategies that will be implemented in the energy
sector over the next few decades. The conference confirmed
the urgent need to adopt strategies to reduce the use of fossil fuels in
order to reduce the emissions responsible for the Serra effect, considered the
primary emergency of the system world energy. The information collected in
these years indicates that there has been a sharp increase in demand for heat and electric energy
and, despite a slow decline and depletion, fossil sources
still account for about 80% of the total energy production. Therefore, it is necessary to undertake actions aimed at
“decarbonizing” the energy sectors as well electrical, thermal and
transport, increasing energy efficiency and using renewable energy sources 1

So, due to the
depletion of fossil resources and increasingly stringent regulations imposed on
environmental pollution throughout the world, alternative energy technologies
have been studied in the recent decades. One of the most interesting and
promising energy technology is the fuel cell.
