What is the purpose of a fuel cell?

What is the purpose of a fuel cell?

A fuel cell uses the chemical energy of hydrogen or other fuels to cleanly and efficiently produce electricity. If hydrogen is the fuel, the only products are electricity, water, and heat.

What are 2 uses of fuel cells?

Fuel cells are used for primary and backup power for commercial, industrial and residential buildings and in remote or inaccessible areas. They are also used to power fuel cell vehicles, including forklifts, automobiles, buses, boats, motorcycles and submarines.

Are fuel cells being used?

Possible Uses. In the future, fuel cells could power our cars, with hydrogen replacing the petroleum fuel that is used in most vehicles today. Many vehicle manufacturers are actively researching and developing transportation fuel cell technologies. Stationary fuel cells are the largest, most powerful fuel cells.

What is fuel cell give example?

Fuel cells are the cells which converts energy of combustion of fuel directly into electricity. Example H2 – O2 fuel cell.

How long do fuel cells last?

The fuel cell stacks are designed to last the lifetime of the vehicle, about 150,000–200,000 miles. At the end of its lifespan, the fuel cell will be disassembled and the materials recycled, similar to what happens with vehicle components today.

Why are batteries better than fuel cells?

The biggest difference between the two is that a battery stores energy, while a fuel cell generates energy by converting available fuel. A fuel cell can have a battery as a system component to store the electricity it’s generating. Essentially, there is a small explosion as the fuel is combusted.

What industries use fuel cells?

10 Industry applications of hydrogen fuel cells.

  • Global Distribution. Fuel cells boast both the range and power required for long-haul trucking and local distribution.
  • Buses.
  • Trains.
  • Personal Vehicles.
  • Planes.
  • Backup Power Generation.
  • Unmanned Arial Vehicles (UAVs)
  • Boats and Submarines.

How do fuel cells produce pollution?

Hydrogen-oxygen fuel cells do not contribute directly to the greenhouse effect as they do not produce carbon dioxide, like other fuels, when they are in use. However, they do still cause pollution . A by-product of this method of production is carbon dioxide, which contributes to the greenhouse effect.

Are fuel cells clean energy?

3. Fuel cells are a clean way to produce power. Fuel cells are similar to batteries in that they produce electricity without combustion or emissions. Unlike batteries, fuel cells do not run down or need to recharge—as long as there’s a constant source of fuel and oxygen.

Can oxygen be used as fuel?

Oxy-fuel combustion is the process of burning a fuel using pure oxygen, or a mixture of oxygen and recirculated flue gas, instead of air. Since the nitrogen component of air is not heated, fuel consumption is reduced, and higher flame temperatures are possible.

What are fuel cells and write its advantages?

Advantages: As reactants are continuously supplied, cell runs and there is no need to replace electrolytes. The only product is water in fuel cells, it is non polluting. Fuel cells have efficiency of 70%. As compared to thermal plants.

What are the advantages and disadvantages of fuel cell?

Expensive to manufacture due the high cost of catalysts (platinum) Lack of infrastructure to support the distribution of hydrogen. A lot of the currently available fuel cell technology is in the prototype stage and not yet validated. Hydrogen is expensive to produce and not widely available.

Which items use fuel cells?

Fuel cell. A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent. Hydrogen is the most common fuel, but hydrocarbons such as natural gas and alcohols like methanol are sometimes used.

What do you need for a fuel cell powered home?

Gather all of the necessary materials. To build a simple household fuel cell, you will need 12 inches (30 cm) of platinum or platinum-coated wire, a popsicle stick, a 9-volt battery and battery clip, clear tape, a glass of water, table salt (optional), a thin metal rod, and a volt meter.

What are the uses of hydrogen fuel cells?

Combustion generates plenty of energy. Hydrogen fuel cells generate electricity from oxygen and hydrogen. These electrochemical cells generate only water vapor so it is considered as environment friendly. Fuel cells are used in spacecrafts, remote weather stations and submarines. When in liquid form, it is used as rocket fuel.

What are some examples of fuel cells?

Different types of fuel cells include polymer electrolyte membrane ( PEM ) Fuel Cells, direct methanol fuel cells, phosphoric acid fuel cells, molten carbonate fuel cells, solid oxide fuel cells, reformed methanol fuel cell and Regenerative Fuel Cells.
