A fuel cell is an electrochemical energy conversion device which produces electricity from external supplies of fuel and an oxidant. They can operate continuously, as long as the flow continues between the fuel and the oxidant. A fuel cell's electrodes are relatively stable, unlike a battery. The most common type of fuel cell is the hydrogen fuel cell, which uses hydrogen as fuel and oxygen as oxidant.
There are also alcohol fuel cells, hydrocarbon fuel cells, and several other types. Fuel cells are considered to have more benefits than other types of fuel due to the fact that fuel cells are more energy efficient and cleaner.
There are a large number of pure plays and semi-pure plays that are publicly traded. The majority of them have negative earnings, and many aren’t even generating any sales, so most of these should be considered very speculative.
The following is the list of most of the major fuel cell players:
