Explanation:

Hydrogen fuel cells convert chemical energy to electrical energy with higher efficiency compared to fossil - fuel combustion. They produce only water as a by - product, creating less pollution. Hydrogen is the most abundant element in the universe, making it a potentially sustainable option. Burning fossil fuels relying on outdated devices is not a reason for hydrogen fuel cells being better, and hydrogen fuel cells being more expensive is a drawback, not an advantage.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.
