    • 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.
    • 本发明涉及一种燃料电池,其包括多个单元膜电极组件,其具有被燃料电极和空气电极夹在中间的电解质膜。 近年来,已经尝试使用燃料电池作为便携式电子设备的电源,并且如果能够使燃料电池小型化,则成为用于便携式电子设备的非常有利的电源系统。 通常,在燃料电池中,多个单位膜电极组件串联电连接,但输出不同的单位膜电极组件的串联连接存在由于单元膜电极组件中发生的极性反转引起的劣化的问题 产量低。 本发明通过燃料电池的结构来解决上述问题,所述结构包括:膜电极组件组,其中多个单元膜电极组件沿圆周方向彼此间隔地设置成预定间隔 围绕给定的中心点,同一电极设置在同一侧; 以及燃料供给机构,其设置在所述膜电极组件组的燃料电极侧,并向所述燃料电极供给燃料。
