How do I Convert a Car Engine to a Fuel Cell Car?

The high cost of gas may have some consumers longing for the elusive hydrogen fuel-cell car.

Cars running on clean hydrogen fuel cells got as far as the prototype stage, but converting a conventional car presents significant, likely insurmountable, logistical challenges to car owners.

How Fuel Cells Work

Fuel cells use hydrogen as a catalyst for a chemical reaction that produces electricity, with only water vapor as a byproduct, making them among the cleanest forms of propulsion.

History

Although the technology appeared in prototypes at least since 2002, no major auto companies, as of 2011, offer hydrogen fuel-cell cars for public purchase. The Obama administration deemed fuel cell vehicles not feasible in the next 10 to 20 years, cutting off funds for their development, Matthew L. Wald reported in the May 7, 2009, edition of "The New York Times."

Conversion Obstacles

You can find kits online, for several hundred dollars, to build fuel cells. In theory, you could mount several in your car, attach an electric motor to each wheel and wire the fuel cells directly to these motors. However, you can't store hydrogen in its gaseous or liquid forms, and it's far more flammable than gasoline. You also won't find filling stations available to the public. Converting your car to electric use as a plug-in, with a kit or via a willing mechanic, presents an alternative.
