Which fact about fuel cells is false?
select one:
a. fuel cells are based on the tendency of some elements to gain electrons from other elements.
b. all of these
c. fuel cell automobiles are whisper quiet.
d. fuel cell automobiles are powered by water and the only emission is hydrogen.
e. fuel cell automobiles are environmentally friendly.

Option (d) is the correct answer.

Explanation:

An electrochemical cell with the help of which chemical energy of a fuel (generally hydrogen) and an oxidizing agent (generally oxygen) are converted into electrical energy by a pair of redox reactions.

A fuel cell is able to generate electricity as long as fuel and oxygen are supplied to it.

As, hydrogen and oxygen are generally used as a fuel so, this results in the formation of water as a by-product.

Thus, we can conclude that the statement fuel cell automobiles are powered by water and the only emission is hydrogen, is FALSE about fuel cells.
