Patent ID: 8003272

Claim:
A fuel cell for a microcapsule-type robot, comprising: a cylindrical fuel cell frame; a cathode to which a fuel is supplied disposed in a region defined by the fuel cell frame; an anode to which an oxidizing agent is supplied disposed in the region defined the fuel cell frame; an electrolyte membrane interposed between the cathode and the anode, the electrolyte membrane dividing the region defined by the fuel cell frame into a cathode side corresponding to the cathode and an anode side corresponding to the anode; alcohol or an aqueous alcohol solution disposed in a space on the anode side; and hydrogen peroxide or an aqueous hydrogen peroxide solution disposed in a space on the cathode side, wherein the fuel cell frame surrounds the space on the anode side and the space on the cathode side, and wherein a first edge and a second edge of the electrolyte membrane contact the fuel cell frame to divide the fuel cell frame into the cathode side and the anode side.
