select all the correct answers. which of these factors make hydrogen fuel cells a better option than burning fossil fuels? hydrogen fuel cells have a higher energy efficiency. hydrogen fuel cells create less pollution. burning fossil fuels relies on outdated devices and technology. hydrogen is the most abundant element in the universe. hydrogen fuel cells are more expensive than fossil fuels.

Explanation:

Hydrogen fuel cells convert chemical energy to electrical energy with higher efficiency compared to fossil - fuel combustion. They produce mainly water as a by - product, resulting in less pollution. Hydrogen is indeed the most abundant element in the universe, which makes it a potentially sustainable fuel source. Burning fossil fuels doesn't necessarily rely on outdated devices, and the fact that hydrogen fuel cells are more expensive is a drawback, not an advantage.

Answer:

Hydrogen fuel cells have a higher energy efficiency
Hydrogen fuel cells create less pollution
Hydrogen is the most abundant element in the universe
