A fuel cell system supplies a reacting solution from a liquid storage section to a reaction section to generate a reacting gas. A gas storage section stores the reacting gas and supplies it to a solid polymer membrane fuel cell which generates electricity using the reacting gas as fuel. The reacting solution is supplied from the liquid storage section to the reaction section when the pressure in the liquid storage section is higher than the pressure in the reaction section and the supply of reacting solution is stopped when the pressure in the liquid storage section is lower than the pressure in the reaction section. In this manner, the supply volume of the reacting solution is controlled in accordance with the driving state of the fuel cell.
