Breakthrough fuel-cell technology promises to make futuristic cars affordable

As any auto show attendee can attest, the cars of the future have long been forecasted to be powered by fuel cells, rather than rely on gasoline for motivation. Durability and affordability have been formidable obstacles to widespread adoption, but that is to change thanks to a breakthrough by a British company.

ACAL Energy has developed a new type of fuel cell that its engineers claim will last up to 300,000 miles without degradation.

Fuel cells combine oxygen and hydrogen to produce electricity, and they emit only water as a byproduct. Almost all recent prototypes demonstrated in cars have been proton exchange membrane fuel cells, which pull oxygen ions through a platinum-coated membrane to bond with the hydrogen. The platinum, which acts as a catalyst to start the chemical reaction, has been the primary issue. Platinum is expensive, heavy, and deteriorates with use. (Learn more about how fuel cells work.)
