Urgency of the thesis Population growth and rapid industrialization of countries especially emerging countries such as China and India lead to rapid demand for energy worldwide. Currently more than 80 of energy needs are met from fossil fuel sources such as oil coal and natural gas because they are available in nature easily and conveniently in transport and storage. However fossil fuel sources are gradually exhausted while increasing demand for energy use has been and will threaten the energy security of many countries as well as bring to the seed of one. On the other hand the use of fossil fuels also creates gas products that pollute the environment. Therefore the need to develop new and alternative energy sources capable of regenerating and not polluting the environment is becoming urgent for humankind. Hydrogen is one of the potential new energy sources in the future hydrogen is the most abundant element its combustion efficiency is higher than petroleum 60 versus 25 . When burning hydrogen there is only one by- product water without any waste that is .
