How do you make hydrogen? How does a hydrogen fuel cell work? What is H2 and how is it used as a fuel? H2, that is, hydrogen fuel, is a molecule consisting of two hydrogen atoms. It is very flammable and can be used as a fuel that doesn’t produce any greenhouse gas emissions s...
Benefits of Hydrogen Fuel Cells Hydrogen fuel cells have the potential to solve some of the biggest problems in energy, from commercial buildings to transportation. These fuel cells can be used in a broad range of applications, from powering cars and other vehicles to entire city blocks. Comp...
Hydrogen fuel cells have come a long way since their inception. They are no longer limited to being used as industrial power systems; instead, they have found their place in the auto industry, providing clean and efficient energy. Since the 1980s, hydrogen fuel cells have seen a surge in p...

Conclusion Hydrogen fuel cells will dramatically change our cars, how are homes and businesses are powered and heated, and it both positively and negatively change places like the Middle East and third world countries. They will also clean up the world's air.WDWN a New...
Fuel cells are a bit like a cross between an internal-combustion engine and battery power. Like an internal-combustion engine, they make power by using fuel from a tank (though the fuel is pressurized hydrogen gas rather than gasoline or diesel). But, unlike an engine, a fuel cell doesn'...
these are hydrogen (H2) and oxygen (O2). Then, you’ve got your electrodes – two per cell, to be exact – which rob your reactants of electrons and pump them into and out of the circuit. In a hydrogen fuel cell, hydrogen enters the cell at an electrode which maintains a ...
How does hydrogen work in a car then? From its tank, the hydrogen is passed through an anode in a fuel-cell. The anode has a catalyst – usually platinum – which forces the hydrogen to split into protons and electrons. The protons get sucked across a ‘proton exchange membrane’ (PEM...
When it comes to power, hydrogen is one of the most energy dense fuels. One kilogram of hydrogen gas generates the same amount of energy as almost three kilograms of gasoline, making the chemical element a highly efficient fuel source. With water and heat as its only by products, hyd...
