Hydrogen fuel cells have a higher energy efficiency, create less pollution and pure hydrogen is more readily available than fossil fuels. Options A, B, and C.
Hydrogen fuel cells offer a more sustainable alternative to burning fossil fuels. Their higher energy efficiency (a) translates to a more effective conversion of chemical energy into electricity.
Moreover, hydrogen fuel cells generate minimal pollution (b), emitting only water vapor and heat. The ready availability of pure hydrogen (d) from diverse sources, including water and natural gas, makes it a versatile and environmentally friendly option.
Contrarily, burning fossil fuels relies on outdated devices and technology (c), contributing to pollution and environmental degradation. Despite initial costs, the long-term benefits position hydrogen fuel cells as a promising and cleaner energy solution.
