PURPOSE: A detecting device of a gas diffusion layer for a fuel cell is provided to measure the physical properties like dimension, surface pollution level, thickness conductivity, flexural strength at one, thereby quickly conducting pre-examination of a gas diffusion layer. CONSTITUTION: A detecting device of a gas diffusion layer for fuel cell comprises: a lower examination jig part(20) measuring the weight and bending strength of a gas diffusion layer and fix mounting a gas diffusion layer at the same time; an upper examination jig part(30) arranged to be able to be moved up and down by a lifting driving unit(50); a plurality of vision examination parts(32) detecting dimension and surface pollution of the gas diffusion layer; a thickness measurement part(34) measuring the thickness of the gas diffusion layer; an eleelectroconductivity measurement part(36) measuring the electric conductivity of the gas diffusion layer; and a control part(40) detecting defective products of the gas diffusion layer.
