In previous articles, I've covered a lot of of alternative energy stocks, including solar energy stocks, wind energy stocks, ethanol stocks, flywheel stocks, a carbon emissions trading stock and geothermal stocks. Today, I'm covering fuel cell stocks.

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. 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 advantageous due to the fact that they are more energy efficient and cleaner than other types of fuel.

The investment arena seems to be flooded with fuel cell stocks and stocks in related industries. Most of them are not generating any earnings, and many aren’t generating revenues. However there are a few that trade on the New York Stock Exchange and generate solid earnings and dividends. Here is the list of most of the major fuel cell players:

The company developed and continues to operate a hydrogen production facility, a fuel cell power plant and a fueling station which dispenses hydrogen and hydrogen blended fuels to a fleet of light duty vehicles in Las Vegas. They also supply Honda Motor Company with high pressure gas and two hydrogen fuelers for their Fuel Cell Vehicle Program with the city of Los Angeles. The stock has a P/E of 22, and is one of the few fuel cell related stocks that pays a dividend, generating a yield of 1.8%.
