A method of selecting a thermoplastic-resin adhesive provided so as to be exposed to a fluid flow path of a power generation cell includes a load application step, an exposing step, a measurement step, and a selecting step. In the load application step, a compressive load is applied to a laminate body in a laminating direction thereof, the laminate body being formed by sandwiching an adhesive between a first resin film and a second resin film. In the exposing step, the laminate body is exposed to an environment heated to a predetermined temperature and humidified to a predetermined humidity. In the measurement step, a flow amount of the adhesive during the exposing step is measured. In the selecting step, the adhesive having the flow amount equal to or less than a predetermined amount is selected as an adhesive used for the power generation cell.
