What is a fuel cell?
A fuel cell is an energy conversion device that combines a fuel and air to directly produce electrical power. Fuel cells offer the promise of high efficiency and low emissions when compared to conventional technologies. If pure hydrogen is used as a fuel, the only products of this process are heat, electricity, and water.
How does a fuel cell differ from traditional methods of energy generation (like batteries)?
Unlike a battery, a fuel cell does not store energy. Instead, it converts energy from one form to another (much like an engine) and will continue to operate as long as fuel is fed to it. However, unlike internal combustion generators, fuel cells convert chemical energy directly into electricity without an intermediate conversion into mechanical power.
What are the benefits of fuel cells?
Fuel cells can provide clean energy for people. Fuel cells emit no pollution when used. The benefits of using fuel cells include:
What are the types of fuel cells?
There are five types of fuel cells and they are defined by the type of electrolyte used in the fuel cell. These include:
What are the types of PEM fuel cells?
There are three main types of PEM fuel cells:
What is the difference between the various types of PEM fuel cells?
The differences in PEM fuel cells stem from how the hydrogen needed for the reaction is obtained.
Where are fuel cells used?
Fuel cells have many applications today, and the list is growing fast. There are three basic market segments that fuel cells satisfy:
