Abstract: A fuel cell is provided to enable spontaneous feed of oxygen by using no oxygen in the air, thereby avoiding a need for an additional oxygen supplying device and fuel pump and improving the reaction efficiency. A fuel cell comprises: a fuel cell stack(50); an oxygen tank(10) communicated with the cathode(51) of the fuel cell stack and storing oxygen therein; and an oxygen valve(20) interposed between the cathode and the oxygen tank and controlling the oxygen feed from the oxygen tank to the cathode. The oxygen tank and the oxygen valve are designed in the form of a cartridge capable of filling oxygen to the oxygen tank separately.

Abstract: An electric power generating apparatus for movement type equipment and a self-generation system having the same are provided to maximize energy conversion efficiency by using rotation motion and a resonance. An electric power generating apparatus for movement type equipment includes a base(38), a plurality of piezoelectric beams(31), a mass part(32), and guide parts(33,34). The base is mounted on the movement type equipment. The piezoelectric beams are mounted on the base in parallel. The mass part includes a plurality of mounting grooves. The mounting grooves connect the other ends of the piezoelectric beams. The other ends are inserted into the mounting grooves. The guide units guide the mass part to slide the mass part in an X direction which is a direction perpendicular to the piezoelectric beams.
