Abstract: An interfacial adhesion strength measuring apparatus of a gas diffusion layer for a fuel cell is provided. The apparatus includes a pair of load applying parts that are each adhered to outer surfaces of a substrate configuring the gas diffusion layer of the fuel cell and a micro porous layer coated on the substrate and is configured to apply a tension force in a direction in which the substrate and the micro porous layer are separated from each other. A first adhering part is applied to one of the load applying parts and is adhered to the substrate and a second adhering part is applied to the other of the load applying parts and is adhered to the micro porous layer. In addition, the first and second adhering parts contain materials of which contact angles with the substrate or the micro porous layer are different from each other, respectively.
