Abstract
Disclosed is a non-destructive inspection method capable of effectively evaluating adhesion quality of an adhesion portion formed between a cell frame and an EGA without damage to parts or deterioration in durability or adhesiveness of parts. In addition, an EGA-cell frame assembly capable of effectively evaluating adhesion quality of an adhesion portion formed between a cell frame and an EGA by the non-destructive inspection method is provided.
Claims14
A method of inspecting an adhesion portion in a hydrogen fuel cell, the method comprising:
- providing an electricity-generating assembly (EGA)-cell frame assembly by applying an adhesive mixed with polymer particulates between an EGA and a cell frame and then subjecting the EGA and the cell frame to thermocompression;
- imaging a shape of the polymer particulates in an adhesion portion by passing X-rays through the adhesion portion formed between the EGA and the cell frame;
- and
- evaluating adhesion quality of the adhesion portion based on the shape of the polymer particulates.
An electricity-generating assembly (EGA)-cell frame assembly comprising:
- an EGA comprising a membrane electrode assembly (MEA) and a gas diffusion layer (GDL);
- a cell frame comprising a polymer resin;
- and
- an adhesion portion bonding the EGA and the cell frame to each other,
- wherein the adhesion portion comprises an adhesive and polymer particulates mixed with the adhesive.
