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.

they are both synthetic elements
