Hydrogen fuel cell technology represents one of the alternative solutions for future clean energy systems. This report reviews the specific characteristics of hydrogen energy, which recommends it as a clean energy to power stationary applications. The aim of review was to provide an overview of the sustainability elements and the potential of using hydrogen as an alternative energy source for stationary applications, and for identifying the possibilities of increasing the share of hydrogen energy in stationary applications, respectively.
Hydrogen in fuel cells: An overview of promotions and demotions

Volume 2(2): 1-6 that actually produces the electricity. However, to produce electricity, the propeller or engine must turn the alternator. In order for a fuel cell to produce power, something must supply it with hydrogen and oxygen. Numerous techniques have been employed to supply the fuel cell with the essential hydrogen and oxygen. Some systems use a "fuel reformer" to extract hydrogen from another fuel source such as propane, and can extract oxygen from the surrounding air. Some systems (in laboratory or industrial settings) are designed to be attached to tanks of pure hydrogen and oxygen. The basic principle of the fuel cell is depicted in the Figure 1. The most fascinating technique of obtaining hydrogen, from a renewable energy viewpoint, is to use "electrolysis" to split water into hydrogen and oxygen, which is afterwards kept in tanks and fed into either end of the fuel cell. The "waste" water produced at the end of the fuel cell process is then fed back into the initial water source. A fuel cell generator set up to electrolyze and re-use water is known as a regenerative fuel cell. Any type of fuel cell could be used in a regenerative system, and the water electrolysis could be powered with wind, solar or hydro energy, resulting in a truly clean power system. Fuel cells can power almost any portable devices that normally use batteries. Fuel cells can also power transportation such as vehiclesm as well as provide supplementary power to traditional transportations.

This paper focuses the production, storage and use of the hydrogen as an alternative and sustainable energy storage. It would be a good and sustainable solution to intermittency problem of renewable energy. Wind and solar e nergy plants are generating immense energy, but the main issue is to deliver that energy to the grid power demand. Transportation of the energy is compelling and costly industry and hydrogen would be a solution to distribute the necessary energy to demanded regions. This project will include subtopics such as; specifics of hydrogen in terms of energy, converting electricity into hydrogen: electrolysis, hydrogen production, hydrogen storage, hydrogen re-electrification, application of hydrogen energy, hydrogen fuel for vehicles and future of hydrogen. Hydrogen is the most promising energy resource since it creates zero-emission. When comparing Hydrogen gas to any other fuel sources, it has the largest energy content. Hydrogen provides us to produce electricity all the time and due to this reason, it is better than wind and solar energy.
The idea of converting chemical energy of fossil fuels directly into electricity already existed around the 1900, and resulted in large-scale experiments trying to oxidize coal and coal gas electrochemically in "piles".
" HYDROGEN AS FUEL. FROM ELECTROLYSIS TO FUEL CELLS "
STEM approach is a well-known pedagogical and teaching method, especially for Natural Sciences teachers. This is because Scientific is based on the major steps of STEM approach. Primarily, a scientific question is being applied, or a science theory had to be tested. Then we were asked to test the theory or attempt to provide some answers to our scientific questions. We have then to perform an experiment using technology and engineering. Finally, in order to process our findings, we must use mathematical approaches. We followed these major steps to compose an educational scenario about water electrolysis and how Hydrogen as an electrolysis product can be used as fuel. We mainly focused on experimentation (electrolysis apparatus) and manufacturing of a compact fuel cell that consumes hydrogen and product's energy. We integrated this STEM approach under a historical frame regarding water as a power source since hundred years ago.
