Water Fuel Cell vs.
Hydrogen Fuel Cell

On this page I will compare and contrast the water fuel cell to the hydrogen fuel cell in hopes of clarifying the similarities and differences between the two completely opposite devices. First, let's compare the two devices to see how they are similar.

Water Fuel Cell and Hydrogen Fuel Cell Compared

1. Can use water to create hydrogen
2. Useful for low emissions or zero emissions
3. Vehicle does not run on 100-percent water

Now, let's contrast these two devices to see what the major differences in technology and application are.

Water Fuel Cell and Hydrogen Fuel Cell Contrasted

1. Water fuel cell electrolyzes water to create hydrogen and oxygen gases (oxyhydrogen or HHO gas). A hydrogen PEM fuel cell can only create hydrogen from water if you run it in reverse. Normally, a fuel cell uses compressed hydrogen gas and oxygen from the air to create and electrical charge and turn an electric motor.
2. Water fuel cell creates HHO gas to supplement a gasoline engine and help it to burn more cleanly, completely and get better mileage. A hydrogen fuel cell is zero emissions (heat and water are the only byproducts) and is really an electric car since it turns an electric motor or motors.
3. Water fuel cell starts with water, creates HHO gas and this gas combusts along with gasoline in the vehicle's cylinders. A hydrogen fuel cell starts with compressed H2 (probably created from natural gas) that is held in a high pressure tank inside the vehicle. The hydrogen is feed into the fuel cell, where it creates electrical current from the H2 and O2 ions traveling different pathways around the Proton Exchange Membrane (PEM).

So, by now you see that a water fuel cell is an aftermarket add-on device that one puts upon their gasoline, diesel, propane, ethanol, or CNG vehicle to help it run more cleanly and efficiently.

A hydrogen fuel cell vehicle, on the other hand, is really an electric car that uses hydrogen and the PEM fuel cell as its "battery."

Oh, yes, and water fuel cells are available now and will help improve gas mileage and lower emissions today, while hydrogen fuel cell cars are a few years off from being commercially viable since there are only about 60 hydrogen refueling stations in the U. S. right now.

So, the choice is yours. Act now and save money, gas and the environment or wait 5 to 10 years or more for hydrogen cars to show up in showrooms.
