MICRO FUEL BATTERY OF SINGLE ELECTRODE TYPE

摘要

PURPOSE: A micro fuel battery of a single electrode type is provided to realize a compact size by constructing an electrode stack of a direct methanol fuel battery arranging a plurality of single electrodes on an electrolyte and a separation plate. CONSTITUTION: In a micro fuel battery of a single electrode type, an external case(10) is made of a porous material, and has a plurality of ventilation holes(20) formed on a top part. A unit battery collection body(17) has a plurality of unit batteries(16) which are arranged on the same plane in the external case. A fuel storing room(18) is formed at current collector body of the unit battery collection body(17), and supplies a fuel to each unit battery. A nonconductive separator(19) electrically isolates the unit batteries.
