Fuel cells are used in spacecraft to produce electricity.
In the cell, hydrogen gas and oxygen are used up. Water is produced.
The graphite electrodes are coated with nickel to speed up the reaction and are seperated by an electrolyte.
a) Write a formula for this equation (no need to balance it!)
b) Apart from providing electricity, suggest another reason why the fuel cell is useful in a spacecraft?
