A hydrogen fuel cell is an electrochemical power generation device that directly converts chemical energy into electrical energy. It is strictly a power generation device, not a storage device. The electrodes of hydrogen fuel cells are made of special porous materials, which is a key technology of hydrogen fuel cells.
Hydrogen-oxygen fuel cells are devices that generate electricity through a chemical reaction between hydrogen and oxygen, with Sir William Grove demonstrating the fundamental idea in 1839.
When a fuel cell is continuously supplied with hydrogen and oxygen, and the product water is removed, the fuel cell can generate electricity. Hydrogen fuel cells and batteries are both electrochemical cells. They each have two electrodes in contact with a material that can conduct ions, called an electrolyte.
They produce much smaller quantities of greenhouse gases and none of the air pollutants that create smog and cause health problems. If pure hydrogen is used as a fuel, fuel cells emit only heat and water as a byproduct. Hydrogen-powered fuel cells are also far more energy efficient than traditional combustion technologies.
Hydrogen fuel cells and batteries are both electrochemical cells. They each have two electrodes in contact with a material that can conduct ions, called an electrolyte. One electrode is the anode and the other is the cathode.
Hydrogen and Oxygen are used to generate electricity, with no combustion involved. Electricity and water are the inputs, while hydrogen and oxygen are the outputs. Conversely, hydrogen can be produced using electricity in a process called electrolysis, operating like a fuel cell in reverse.
