Abstract
A fuel cell for a microcapsule-type robot uses alcohol or an aqueous alcohol solution as a fuel and was hydrogen peroxide or an aqueous hydrogen peroxide solution as an oxidizing agent. A microcapsule-type robot also uses the fuel cell. The fuel cell may be used in a microcapsule-type endoscope and have an operating time that is long enough to diagnose human organs. The fuel cell may comprise hydrogen peroxide as an oxidizing agent instead of air or oxygen such that the fuel cell can operate inside the human body. Thus, an oxygen source, which cannot be obtained in a human body, can be easily supplied to the fuel cell, and the fuel cell has higher performance than a fuel cell in which air is used as an oxidizing agent.
