Zusammenfassung:The present invention relates to a metal air battery using magnets to facilitate replacement of an air anode. According to the present invention, the metal air battery comprises: a body (10) having an open receiving part (11) between the upper and lower parts formed on the front and rear surfaces to accommodate the air anode support (60), having an electrolyte outlet (14) formed at the lower end and through which an electrolyte is discharged, and having an insertion hole (15) formed on the upper part and into which a metal cathode (20) is inserted; the metal cathode (20) installed to be inserted into the body (10); a cover (30) fixing the metal cathode (20) while opening and closing the upper part of the opened body (10); the cathode terminal (40) positioned on the upper surface of the cover (30) and fastened to the metal cathode (20); an air anode (50) allowing the air to flow in and out, preventing the electrolyte from flowing out, and coming in close contact with the receiving part (11) on both sides of the body (10); an air anode support (60) having a size corresponding to that of the receiving part (11) of the body (10), fixing the air anode (50) to the receiving part (11) of the body (10) while supporting the outer surface of the air anode (50), and having a through-hole (62) formed so that the outer surface of the air anode (50) is exposed to the outside; and an anode terminal (70) surrounding a side surface of the body (10) and having one end and the other end in close contact with the outer surface of the air anode (50). A fixed magnet (16) is formed on the surface of the receiving part (11) of the body (10) and exposes either the N pole or S pole thereof. A fixed magnet (61) is fixed on the inner surface of the air anode support (60) and exposes an opposite pole at a position corresponding to the fixed magnet (16) of the body (10). 본 발명에 따른 자석을 이용한 금속공기전지는 전면과 후면에는 공기양극 지지체(60)를 수용할 수 있도록 상부와 하부 사이의 개구된 수용부(11)가 형성되고, 하단에는 전해질이 배출되는 전해질 배출구(14)가 형성되며, 상부에 금속음극(20)이 삽입되는 삽입공(15)이 형성된 몸체(10)와; 몸체(10)의 내부로 삽입되도록 설치되는 금속음극(20)와; 개구된 몸체(10)의 상부를 개폐되면서 금속음극(20)을 고정시키는 뚜껑(30)과; 뚜껑(30)의 상부면에 위치하면서 금속음극(20)에 체결되는 음극단자(40)와; 공기의 출입은 가능하지만 전해질은 밖으로 유출되지 않으며 몸체(10) 양측면의 수용부(11)에 밀착되는 공기양극(50)과; 몸체(10)의 수용부(11)에 대응되는 크기를 갖으며 공기양극(50)의 외면을 지지하면서 공기양극(50)이 몸체(10)의 수용부(11)에 고정시키며 공기양극(50)의 외면이 외부에 노출되도록 관통공(62)이 형성된 공기양극 지지체(60)와; 몸체(10)의 측면을 감싸면서 일단과 타단이 공기양극(50)의 외측면에 밀착되는 양극단자(70);를 포함하고, 몸체(10)의 수용부(11)의 표면에는 N극 또는 S극의 어느 한 극이 노출되는 고정자석(16)이 형성되고, 공기양극 지지체(6
