Abstract
An electronic device is provided with a fuel cell which is formed to introduce air from at least two surfaces of a casing of the fuel cell and to supply a fuel from an inside of the casing for high energy efficiency. The fuel cell is structured to form an air-supply space between the fuel cell and the electronic device and mounted in a manner that the surface of the fuel cell, which is on a reverse side of the surface facing the electronic device, is exposed to the ambient air. The electronic device is provided with a fuel cell structured to supply air from at least two surfaces of the casing to achieve better energy efficiency.
