What Is A Fuel Cell? And What Is The Carbon Nanotube Revolution?

 To compare, the typical internal combustion engine of a car is about 25% energy efficient. They are compact and lightweight, with no major moving parts, and can achieve up to 99.9999% reliability. They are ideal in remote locations, like spacecraft, reservation parks, weather stations, rural locations, secluded research stations, and in military applications.

Basically, a fuel cell is a device that produces electricity from a fuel source, usually hydrogen. This is done through a chemical reaction where a catalyst is used, which has traditionally been platinum. Unfortunately, however, as platinum is very expensive, this technology has not been very economically viable.

Finding a cheaper replacement to use as a catalyst has been a major area of research for decades recently, however, scientists have been developing an alternative in carbon nanotubes.
