The 21st century has been marked by numerouschanges concerning the way we understand and use energy.
During the recent Paris Conference, it was decided unanimously toconsiderably reduce the use of fossil fuels to reduce the emission. It will certainly have a majorimpact on the future energy strategies that will be implemented in the energysector over the next few decades. The conference confirmedthe urgent need to adopt strategies to reduce the use of fossil fuels inorder to reduce the emissions responsible for the Serra effect, considered theprimary emergency of the system world energy. The information collected inthese years indicates that there has been a sharp increase in demand for heat and electric energyand, despite a slow decline and depletion, fossil sourcesstill 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 andtransport, increasing energy efficiency and using renewable energy sources 1So, due to thedepletion of fossil resources and increasingly stringent regulations imposed onenvironmental pollution throughout the world, alternative energy technologieshave been studied in the recent decades. One of the most interesting andpromising energy technology is the fuel cell.
