A.
Decomposing water requires a high activation energy.
B.
The Sun isn't a renewable resource.
C.
Decomposing water results in toxic byproducts.
D.
Scientists are uncertain what to do with the excess oxygen.

Answer:
A.
Decomposing water requires a high activation energy.
Explanation:
The challenge that scientists will face with this task is the production of hydrogen since hydrolysis or the decomposition of water (H2O) requires a certain amount of energy to be supplied. Scientists should look at how much is this energy supplied. It can be more than what would be produced from the fuel cells which will eventually result to a loss.
