What are advantages and disadvantages of fuel cells?

What are advantages and disadvantages of fuel cells?

Good reliability- quality of power provided does not degrade over time. Noise- offers a much more silent and smooth alternative to conventional energy production. Environmentally beneficial- greatly reduces CO2 and harmful pollutant emissions.

What are the advantages of fuel cells over batteries?

Fuel cell electric vehicles have a much higher energy density by weight, allowing them to overcome the range and weight challenges associated with battery electric vehicles. Hydrogen tanks are also more compact and lighter than an array of fully charged batteries.

What are 3 advantages of hydrogen fuel cells?

What are The Advantages of Hydrogen Fuel Cells?

  • Renewable and Readily Available.
  • Hydrogen is a Clean and Flexible Energy Source to support Zero-Carbon Energy Strategies.
  • More Powerful and Energy Efficient than Fossil Fuels.
  • Highly Efficient when Compared to Other Energy Sources.
  • Almost Zero Emissions.

Why are fuel cells Bad?

Hydrogen fuel cells have bad theoretical and practical efficiency. Hydrogen storage is inefficient, energetically, volumetrically and with respect to weight. It has a horrible well-to-wheel efficiency as a result. Easy ways to get large quantities of hydrogen are not ‘cleaner’ than gasoline.

Why hydrogen is a bad idea?

Why are hydrogen cars not used?

The sceptics’ first argument against hydrogen vehicles is that they’re less efficient than EVs are. Because hydrogen doesn’t occur naturally, it has to be extracted, then compressed in fuel tanks. It then has to mix with oxygen in a fuel cell stack to create electricity to power the car’s motors.

Is fuel cell profitable?

The company is still not expected to be profitable anytime soon. This means FCEL stock remains unmoored to any kind of normal investment reality. However, investors seem to be highly energized by the recent Congressional passage of an alternative fuels tax credit.
