PURPOSE: A gas permeability measurement apparatus is provided to measure gas permeability of a gas diffusion layer of PEMFC under a real cell operation condition and to improve the performance of PEMFC. CONSTITUTION: A gas permeability measurement apparatus for a gas diffusion layer of PEMFC under real cell operation condition includes a gas feed part, a first chamber connected to the gas feed part, a second chamber(102) connected to the first chamber through a gas path, a membrane cell(400) which is installed at the gas path communicating the first chamber and the second chamber and has a gas diffusion layer sheet interposed therebetween, and a pressure measurement part(103) for measuring pressure difference between the first chamber and the second chamber. |
