How do fuel cells work?

How do fuel cells work?

How Fuel Cells Work. Fuel cells work like batteries, but they do not run down or need recharging. They produce electricity and heat as long as fuel is supplied. A fuel cell consists of two electrodes—a negative electrode (or anode) and a positive electrode (or cathode)—sandwiched around an electrolyte.

How can fuel cells be used in the future?

Possible Uses. In the future, fuel cells could power our cars, with hydrogen replacing the petroleum fuel that is used in most vehicles today. Unlike a typical battery, which eventually goes dead, a fuel cell continues to produce energy as long as fuel and oxidant are supplied.

Are hydrogen fuel cells being used?

Hydrogen fuel cells will likely be used in stationary power devices and portable devices followed by transportation applications. Most of the automobile manufacturers are analyzing the latest prototypes of hydrogen fuel cell vehicles.

Which one is the disadvantage of hydrogen fuel?

Disadvantage: Hydrogen Storage and Transportation Hydrogen can be stored as either gas in high-pressure tanks or as a liquid in cryogenic temperatures, but it must be in the gas form to be used for lift truck fuel cells. Both methods of hydrogen storage involve an inherent loss of energy.

Are fuel cells expensive?

Fuel cells are very costly because they are complex and require expensive materials such as platinum.

Why is the fuel cell so expensive?

Fuel cells are very costly because they are complex and require expensive materials such as platinum. Hydrogen in vehicles must be compressed in expensive high-pressure tanks as well. That is the reason why it is expensive currently.

Are fuel cell cars safe?

They aren’t tied to an electric plug. They produce zero emissions from the tailpipe and can deliver 300 miles or more per tank of fuel. They can be refilled as fast — or faster — than a conventional car with a 15-gallon gas tank. After extensive testing, researchers say they are as safe to drive as gasoline cars.

How far can a fuel cell car go?

Other benefits include increasing U.S. energy security and strengthening the economy. FCEVs are fueled with pure hydrogen gas stored in a tank on the vehicle. Similar to conventional internal combustion engine vehicles, they can fuel in less than 4 minutes and have a driving range over 300 miles.
