A fuel cell system has a liquid storage portion (1) for storing a reaction solution, a reaction portion (2) for generating a reaction gas from the reaction solution supplied from the liquid storage portion (1), a gas storage portion (3) for storing the reaction gas supplied from the reaction portion (2), and electrodes arranged in a state where they are joined to a solid polymer electrolyte film. The fuel cell system further has a fuel cell and reaction solution supply amount-regulating means. The fuel cell generates power using as fuel the reaction gas supplied from the gas storage portion (3). The reaction solution supply amount-regulating means supplies the reaction solution from the liquid storage portion (1) to the reaction portion (2) when the pressure of the liquid storage portion (1) is higher than that of the reaction portion (2), and stops the supply of the reaction solution when the pressure of the liquid storage portion (1) is lower than that of the reaction portion (2). The above structure enables the amount of supply of the reaction solution to be controlled in accordance with drive condition of the fuel cell. |
