Question

What are pros and cons of hydrogen fuel cells?

Answer 1

The pros of hydrogen fuel cells are that they are very efficient, producing very little waste. They are also very stable, which makes them safe to use.

The cons of hydrogen fuel cells are that they can be expensive to produce and maintain, and they require a lot of energy to power them, meaning that they often aren't as efficient as they could be.

Despite these pros and cons, hydrogen fuel cells are still a very promising technology. With more research, attention, and development, they could be a powerful force in the fight against carbon emissions and global warming.

Answer 2

Pros: No vehicle emissions other than water vapor. Fuel economy equivalent to about twice that of gasoline vehicles. Hydrogen is abundant, and can be made from renewable energy. Cons: This space-age technology is expensive.
