Abstract: A micro fuel cell with no electrolyte film is provided to prevent the exhaustion of reactants on the surface of electrodes by removing the direct mixing of cathode fluid and anode fluid and to improve the efficiency of a fuel cell. A micro fuel cell with no electrolyte film comprises a plurality of unit cells(100). Each unit cell comprises a cathode channel(110) segmented to flow the cathode fluid, anode channel(120) segmented to flow the anode fluid, and a connection pathway(130). The connection pathway connects the interval of the cathode channel and the anode channel, forms a boundary of the cathode fluid and the anode fluid, and is mixed by the diffusion.

Abstract: 본 발명의 전해질막이 없는 마이크로 연료 전지에 관한 것으로서, 양극 채널과 음극 채널을 따라 낮은 레이놀즈 수를 가지고 흐르는 양극 유체와 음극 유체가 미세 연결 통로를 통해 이들의 경계면을 이루며 확산에 의해서만 혼합이 이루어지도록 구성되어, 양극 유체와 음극 유체의 직접적인 혼합을 제거하여 전극 표면에서의 반응물이 고갈되는 것을 방지하고, 아울러 연료 전지의 효율을 증가시킬 수 있도록 한다.

Abstract: A cation exchange membrane fuel cell is provided to increase the contact area of the fuel flowing into the upper fuel channel of a membrane electrode assembly and the air flowing into the lower air channel, thereby improving the uniformity of local current density distribution and temperature distribution and preventing the thermal twisting of a battery. A cation exchange membrane fuel cell comprises an upper separator(10) where a short upper shoulder(12) and a long upper shoulder(14) are formed alternatively; a lower separator(24) where a long lower shoulder(18) corresponding to the short upper shoulder and a short lower shoulder(20) corresponding to the long upper shoulder are formed alternatively; and a membrane electrode assembly(26) where the upward inclination and the downward inclination are formed alternatively and which is formed between the upper separator and the lower separator.
