What are the advantages and disadvantages of using hydrogen 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 are fuel cells not environmentally friendly?

Fuel cells, using processed fossil fuels, have emissions of CO2 and sulfur dioxide (SO2) but these emissions are lower than those from traditional thermal power plants or spark ignition engines due to the higher efficiency of fuel cell power plants.

What are fuel cells explain the advantage of fuel cells?

Why Study 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 the advantages of hydrogen fuel cells?

As with fuel cells, the main waste product is water, not carbon dioxide. Also, unlike gasoline, hydrogen burns well in “fuel-lean conditions,” where there’s a lot more oxygen than fuel. That’s good for fuel efficiency and also vastly reduces nitrogen oxide emissions. How about using hydrogen in stationary applications?

Are hydrogen-powered vehicles the answer to climate change?

Heavily dependent on fossil fuels for energy, the transportation sector contributes to a staggering 20 percent of carbon dioxide emissions globally. Hydrogen-powered vehicles could be the answer to this problem, as fuel cell vehicles, which use hydrogen gas to power an electric motor, emit only heat and water as by-products.

Can hydrogen replace fossil fuel in personal transportation?

A decade ago, it seemed like there were two potential contenders to replace fossil fuel for personal transportation – electricity and hydrogen. The hydrogen option had a lot going for it. You could fill your car up just like fossil fuel, but instead of noxious gases coming out of the tailpipe, the exhaust would just be pure water vapour.

Which companies are leading the hydrogen fuel cell Revolution?

Toyota was one company that truly believed in the hydrogen future, and produced the very credible FCV-R concept in 2011 that developed into the Mirai, which became commercially available in 2015. A second generation will be released in 2021. Honda has also produced a couple of fuel cell vehicles, the Clarity Fuel Cell and FCX Clarity.
