  • Fuel cell, fuel cell system and electronic device
    Patent number: 9059443
    Abstract: There are provided a fuel cell having stable and good power generation characteristics and good safety, a fuel cell system including the fuel cell and an electronic device equipped with the fuel cell. The fuel cell includes at least an electrolyte membrane, an anode formed on one surface of the electrolyte membrane, a cathode formed on the other surface of the electrolyte membrane, a liquid fuel chamber for supplying a liquid fuel to the anode, and a separating layer formed between the anode and the liquid fuel chamber. The separating layer and/or the anode has an exhaust passage that is continuously formed in an in-plane direction to discharge exhaust gas generated at the anode. The separating layer allows the liquid fuel to pass from the liquid fuel chamber to the anode and blocks the movement of gas from the anode to the liquid fuel chamber.
