This membrane separates the anode and the cathode sides in the fuel cell system. Hydrogen is diffused on the anode side of the fuel cells, producing protons that travel through the membrane to the cathode.The electrons produced by the process are fed into an external circuit, thus creating an...
These fuel cells can be used in a broad range of applications, from powering cars and other vehicles to entire city blocks. Compared to conventional gasoline vehicles, hydrogen fuel cell vehicles can even reduce the amount of carbon dioxide being produced. If the hydrogen is produced by ...

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...
In recent years,hydrogenfuel cells have proven immensely scalable and have come to be used in growing numbers of planes, trains and automobiles (if you’d like more information on this, take a look at our articles on each of these developments). For many, however, these fuel cells...
Why Use Fuel Cells? How Fuel Cells Work If you want to be technical about it, a fuel cell is an electrochemical energy conversion device. Discovered in the 1800s, a fuel cell converts the chemicals hydrogen and oxygen into water, and in the process it produces electricity. ...
How does a fuel cell make electricity from hydrogen? What happens in a fuel cell is called an electrochemical reaction. It's a chemical reaction, because it involves two chemicals joining together, but it's an electrical reaction too because electricity is produced as the reaction runs its ...
"It's also a clean, high-energy-content molecule that can be used in fuel cells or to store energy generated by variable power sources like solar and wind. But most of the hydrogen produced today is made with fossil fuels, adding to the level of CO2 in the atmosphere. We need a cost...
Outcome and Impact: “The results showed that an alloy catalyst significantly improved the efficiency of hydrogen fuel cells compared to traditional, single-element catalysts. This discovery, although on a small scale, contributed valuable data to the ongoing research in sustainable energy solutions. ...
Fuel cell-powered vehicles are still the way of the future ... if they can dodge a few big stumbling blocks.
