In a fuel cell system which dilutes a liquid fuel to supply the diluted liquid fuel to an anode, it is intended to achieve stable electricity generation capacity. The fuel cell system generates electricity by an electrochemical reaction between the liquid fuel and an oxidant, and this system comprises a cell which generates electricity by the electrochemical reaction; a fuel container containing the liquid fuel of high concentration; and a buffer tank which dilutes the liquid fuel in the fuel container to supply the diluted liquid fuel to the anode of the cell, wherein an electromagnetic valve is provided in a fuel supply path between the fuel container and the buffer tank to prevent the liquid fuel from flowing back from the buffer tank to the fuel container.
