The invention provides for a material characterization system, method, and instrumentation for measuring the mechanical properties of nano-scale thin films. The thin film mechanical characterization system, method, and instrumentation of the present invention for ultra-thin films includes a motor and load cell. The instrumentation device includes a bath that can be filled or used with liquid so that a thin film can float via the surface tension and can be stretched until permanent deformation occurs, while recording the amount of force applied by the motor and other parameters. Further, the invention provides a process that transfers the nano-scale thin film to the tensile testing instrument and a process to obtain the physical mechanical properties of thin films that are at the nanoscale level.

In an inspection method for inspecting occurrence of a deformation in a fuel cell, a change amount between a pressure loss parameter value before an impact and a pressure loss parameter value after the impact is found, and when the change amount is a reference value determined in advance or more, it is determined that the deformation occurs inside the fuel cell. It is determined that the deformation occurs inside the fuel cell due to the impact, in at least either of a case where the change amount of a first pressure loss parameter value that is a pressure loss parameter value in a gas passage is a first reference value or more and a case where the change amount of a second pressure loss parameter value that is a pressure loss parameter value in a refrigerant passage is a second reference value or more.
