What are the advantages and disadvantages of fuel cells?

Hydrogen Fuel Cell Advantages and Disadvantages in Material…

  • Hydrogen Fuel Cell Technology.
  • Advantage: High Energy Density Improves Productivity.
  • Disadvantage: The Use of Fossil Fuels in Hydrogen Production.
  • Disadvantage: Hydrogen Storage and Transportation.
  • Disadvantage: Fuel Cell Efficiency.

Why is energy density important in fuels?

Energy stored in a given volume of fuel – higher volume-energy density means less space is require to store the fuel in the vehicle, which can result in less space needed for a fuel storage facility on the vehicle.

What are the disadvantages of using hydrogen as a fuel?

List of Disadvantages of Hydrogen Fuel Cells

  • It is expensive. While widely available, hydrogen is expensive.
  • It is difficult to store. Hydrogen is very hard to move around.
  • It is not easy to replace the existing infrastructure.
  • It is highly flammable.
  • Fossil fuels are often used to produce it.

What are the Disadvantages of Fossil Fuels?

  • Fossil Fuels are Nonrenewable. Non-renewable energy resources are estimated to deplete in the near future.
  • Dangerous to Produce.
  • Refinery and Oil Rig Explosions.
  • Water Pollution and Oil Spills.
  • Water Table Poisoning from Fracking.
  • Air Pollution and Smog.
  • Acid Rain.
  • Mercury Emission.

What is a fuel cell and what are the advantages of the fuel cells?

Fuel cells can operate at higher efficiencies than combustion engines and can convert the chemical energy in the fuel directly to electrical energy with efficiencies capable of exceeding 60\%. Fuel cells have lower or zero emissions compared to combustion engines.

What are some advantages and disadvantages of biomass energy?

Biomass Energy Advantages And Disadvantages: What are the major Pros & Cons?

Advantages of Biomass Energy Disadvantages of Biomass Energy
It is Renewable It’s Not Completely Clean
Carbon Neutrality High Costs In Comparison To Other Alternatives
Less Dependency On Fossil Fuels Possible Deforestation
It Is Versatile Space

What is the major disadvantage of LPG as a fuel in the automobile *?

reduction in
Explanation: The major disadvantage of LPG is the reduction in the life of the engine and less power compared to gasoline. The other disadvantage of LPG is a special fuel feed system is required for liquid petroleum gas (LPG).

Is a higher density in fuel better?

In energy storage applications the energy density relates the energy in an energy store to the volume of the storage facility, e.g. the fuel tank. The higher the energy density of the fuel, the more energy may be stored or transported for the same amount of volume.

How does density affect fuel?

Density. Density is an important fuel property with respect to volumetric fuel economy and maximum power. In general, the energy per unit volume increases with increasing density.

What are the advantages of using hydrogen as a fuel class 11?

The cleanest fuel available when combusted produces no carbon residues. Highly efficient when compared to other energy sources.

What are advantages and disadvantages of renewable energy?

Advantages and disadvantages of renewable energy

Advantages Disadvantages
• Renewable energy won’t run out • Renewable energy has high upfront costs
• Renewable energy has lower maintenance requirements • Renewable energy is intermittent
• Renewables save money • Renewables have limited storage capabilities

What are the advantages of fuel storage?

High energy content per liter (only when stored as liquid form) Physical delay of fuel is almost zero. Good load response. Clean combustion of fuel and low emission. Since there is no carbon in the fuel, there is would be no carbon monoxide and hydrocarbons in the exhaust gas. Even fuel leakage to the environment does not consider as pollution.

What are the advantages of hydrogen energy?

Easy production – Hydrogen can produce by many chemical processes including simple electrolysis of water. Reduce the dependency on fossil fuel. High energy content per liter (only when stored as liquid form) Physical delay of fuel is almost zero. Good load response. Clean combustion of fuel and low emission.

What are the disadvantages of oil as an energy source?

Disadvantages of Oil Energy 1 Is a Non-renewable and Fast Depleting Energy Source. Oil is a reliable source of power (like all the other fossil fuels), but at the same time is a finite 2 Is a Major Source of Air, Water and Soil Pollution. 3 Mining of Oil is Another Activity Affecting the Environment. 4 The Price of Oil Keeps Rising.

What are the advantages of petroleum as a fuel?

The fuel is stable, even in storage, and that advantage allows us to create predictable outcomes once we can harvest petroleum from the rock strata, tar sands, or seeps where it occurs naturally. 3. We use petroleum to make renewable energy products.
