Summary: | The present invention relates to a device for measuring the water permeability of a gas diffusion layer for a fuel cell, which is capable of shortening the measurement time through a measurement device that simulates a fuel cell stack and preventing damage to a sample. The device for measuring the water permeability of a gas diffusion layer for a fuel cell according to one embodiment of the present invention comprises: a lower plate fixture of which a water tank where a gas diffusion layer is seated is provided on an upper surface; an upper plate fixture disposed on the top of the lower plat fixture while being spaced apart therefrom and configured to press the gas diffusion layer seated on the lower plate fixture; and a detection label which is disposed on a lower surface of the upper plate fixture, is arranged to face an upper surface of the gas diffusion layer and is configured to react when in contact with water passing through the gas diffusion layer from the water tank.
본 발명은 연료전지 스택을 모사한 측정장치를 통하여 측정시간을 단축하면서 시료의 손상을 방지할 수 있는 연료전지용 기체확산층의 물투과도 측정장치에 관한 것이다. 본 발명의 일 실시형태에 따른 연료전지용 기체확산층의 물투과도 측정장치는 연료전지용 기체확산층의 물투과도를 측정하는 장치로서,상면으로 기체확산층의 안착되는 수조가 구비되는 하판치구와; 상기 하판치구의 상부에 이격되어 배치되어 상기 하판치구에 안착된 기체확산층을 가압하는 상판치구와; 상기 상판치구의 하면에 배치되되, 상기 기체확산층의 상면에 대면되도록 배치되어 상기 수조로부터 상기 기체확산층으로 투과되는 물과 접촉되면 반응되는 검출라벨을 포함한다. |
