Free QuoteA typical hydrogen fuel cell produces 0.5 V to 0.8 V per cell. To increase the voltage individual cells can be connected in series. This arrangement is called a fuel cell stack. The cross sectional area of a fuel cellaffects its ability to produce current. Greater area means more reaction sites, and this allows more current to be generated.
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.
A hydrogen battery, also known as a fuel cell, generates electricity by combining hydrogen and oxygen. At the anode, a catalyst divides hydrogen into protons and electrons. Protons move through the electrolyte to the cathode, while electrons travel through an external circuit, creating electricity. This process also produces water as a byproduct.
This chemical energy is stored in the hydrogen that is supplied to the anode of the fuel cell. A hydrogen fuel cell essentially consumes hydrogen and oxygen. 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. One electrode is the anode and the other is the cathode.
Fuel cells can produce electricity continuously for as long as fuel and oxygen are supplied. The first fuel cells were invented by Sir William Grove in 1838. The first commercial use of fuel cells came almost a century later following the invention of the hydrogen–oxygen fuel cell by Francis Thomas Bacon in 1932.
