Fuel cells are a technology used to create electricity by combining hydrogen gas with oxygen from the air. Like a battery, these cells convert chemical energy directly into electricity. But a fuel cell does not need to be recharged because, as long as it is supplied with hydrogen, it will continue to produce electricity. Hydrogen can be produced from gasoline, ethanol, natural gas and methanol. It can also be produced from water by electrolysis. Hydrogen cannot be produced by any completely renewable resources as of yet, but the possibility is still being researched.
Fuel cells are currently being used to power motors in electric powered vehicles, also called EVs. Some advantages to having an electric powered vehicle are that they produce no emmisions, increase fuel efficency, lower maintenance costs to your motor, and are quiter than a conventional engine. Although there are still some disadvantages to fuel cells, such as finding safe ways to store hydrogen, reducing the cost of electric vehicles, creating durable vehicles, and developing an infrastructure for fuel cell power, particularly filling stations that offer hydrogen.
