Which of the following statements best describes the difference between
hydrogen fuel cells and hydrogen fusion?
A. More energy is produced per reaction in a fusion reaction than in a
fuel cell
B. The energy for a fuel cell reaction follows the equation:
2
E = mc1
The energy for a fusion reaction does not.
C. The energy produced from a single atom of hydrogen in a fuel cell
is the same as the energy produced from a single atom of
hydrogen in a fusion reaction.
D. Fusion reactions produce more energy because they use more
hydrogen than fuel cells do

The correct answer is option A. "More energy is produced per reaction in a fusion reaction than in a fuel cell".

Explanation:

It is estimated that a fusion reaction four million times more energetic than traditional chemical reactions such as burning of coal, oil or gas. Fusion reactions produce even more energy than other types of atomic approaches, such as the ones used in hydrogen fuel cells. Hydrogen fuel cells are based on the energy produced by hydrogen atoms moving from an anode to a cathode, an energetic approach but not as energetic as the atomic fusion.
