The Fuel Cell

A Fuel Cell is an energy converter that can be used efficiently to convert the chemical energy of hydrogen into electricity and heat.

Imagine that water is the solution for the energy needs on earth!

Fossil-free electricity from Fuel Cells

Imagine that water is the solution for the energy needs on earth! Your accommodation’s power supply is free of charge and can be produced locally. In addition, your vehicle’s fuel is also free and you supply the energy you need nearby, or maybe even where you live.

Hydrogen is also an energy carrier just like electricity. This means that hydrogen is not a primary energy source, but can be used to store, transport and provide energy. The flexibility is great because hydrogen can be produced from all types of energy sources. Hydrogen can be used as energy in fuel cells.

A fuel cell is an energy converter that can be used efficiently to convert the chemical energy of hydrogen into electricity and heat. The residual product is pure water, H2O, when oxygen from the air is used. Fuel cells can replace internal combustion engines in vehicles where they drive electric motors and can also be used to supply energy to houses. They can also be used in smaller devices such as mobile phones, computers or power units for leisure boats. For both portable and stationary applications, there is technology that is commercially available. (source: Vätgas Sweden)

The Fuel Cell

How it works

A Fuel Cell has an anode side and a cathode side that are separated by a membrane. The membrane only allows protons to pass through. On the anode side, a catalyst splits the hydrogen atoms into protons and electrons. The electrons cannot pass the membrane but are led to an external circuit where they generate electricity. The protons pass through the membrane. On the cathode side, the electrons and protons unite and connect to oxygen (O2) from the air. The reaction produces water (H2O). A fuel cell produces about 0.7 volts. To get a higher voltage, many separate fuel cells are combined.

Fuel cell technology will account for at least 25% of the energy supply in Europe within 30 years.

Examples of areas of use

Fuel cell technology is the only 100% fossil-free energy technology where the energy can be used for, for example, operating vehicles or heating houses. By using hydrogen together with fuel cell technology, you get exhaust-free cars and buses where clean water is the only emission. Today, the technology is used worldwide to store solar and wind power, to make homes self-sufficient in energy and to make vehicles completely free of harmful emissions.
