Abstract
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.
