    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： The present invention relates to a fuel cell including a plurality of unit membrane electrode assemblies having an electrolyte membrane sandwiched by fuel electrodes and air electrodes. In recent years, attempts have been made to use fuel cells as power sources of portable electronic devices, and if the fuel cell can be made compact, it becomes a remarkably advantageous power supply system for portable electronic devices. Generally, in the fuel cell, the plural unit membrane electrode assemblies are electrically connected in series, but the serial connection of the unit membrane electrode assemblies different in output has a problem such as the deterioration due to polarity reversal occurring in the unit membrane electrode assembly with a low output. The present invention solves the above problem by the structure in which the fuel cell includes: the membrane electrode assembly group in which the plural unit membrane electrode assemblies are arranged two-dimensionally so as to be a predetermined interval apart from each other in a circumferential direction around a given center point, with the same electrodes being set on the same side; and a fuel supply mechanism disposed on the fuel electrode side of the membrane electrode assembly group and supplying a fuel to the fuel electrodes.
