Which of the following best describes the features of a fuel cell?
a. The process which provides electrical current in a fuel cell is the direct combining of a molecule of oxygen and two molecules of hydrogen to form two molecules of water.
b. A fuel cell is very like a lead-acid battery: energy is stored initially as chemical energy; and the total electrical energy able to be generated depends on the size of the electrodes.
c. fuel cells have no greenhouse gas emissions or other pollutants in their operation, and they are highly reliable.
d. Fuel cells are only able to operate on small scales; it is not practical to make large-scale fuel cells capable of generating tens of kW.
e. The fuel cell can only be charged by running electricity through it in the opposite direction in order to form hydrogen and oxygen; then hydrogen and oxygen provide fuel for the cell to produce electricity.
I would decide between ans b) and d) but if you need to choose one, I would think that it’ll be b) because you were asked about the features and solution b) has provided many features of a fuel cell in the answer.
I’m not really sure but you can take this answer as a reference…I’m kinda sucky at Chemistry. sorry:(

Get a small windmill , use the power to make H2 , store it and drive a fuelcell.
