    摘要： The present invention relates to a fuel cell including: a membrane electrode assembly (2) having a fuel electrode (13), an air electrode (16), and an electrolyte membrane (17) sandwiched therebetween; and a fuel storage unit (4) storing a liquid fuel. The fuel cell is capable of continuously generating electricity for long hours only by being replenished with a fuel, and therefore, attempts have been made to miniaturize the fuel cell to use it as a power source of portable electronic devices. When the membrane electrode assembly and the fuel storage unit in the fuel cell are connected via a flow path, a fuel supply state becomes uneven depending on the shape and the like of the flow path even though a supply amount of the fuel can be adjusted, which causes a problem such as a decrease in an output of the fuel cell. The present invention solves the aforethe problem by providing, in the fuel cell, a fuel distributing mechanism (3) which supplies the fuel to a plurality of places of the fuel electrode, and connecting the fuel distributing mechanism and the fuel storage unit via the flow path (5).

    摘要： An electrode membrane structure includes a solid electrolyte membrane of a polymer material, and a fuel electrode and an air electrode stacked on both sides of the solid electrolyte membrane. The fuel electrode is formed of an anode catalyst layer and a fuel electrode collector, and the air electrode is formed of a cathode catalyst layer and an air electrode collector. At the backside of the fuel electrode collector, a fuel tank is defined between a casing and a fuel holding film. The interior of the fuel tank is divided into a plurality of divisions by a partition to uniformly distribute liquid fuel to the fuel electrode. The liquid fuel (methanol) in the fuel tank is absorbed and held by the fuel holding film, is dispersed through the fuel holding film to the fuel electrode.
