AI Technical Summary

Technical Problem

Existing fuel cell stacks face issues with uniformity of distances between separators due to the use of seal members with low rigidity, affecting dimensional stability during manufacturing.

Method used

A laminated body for fuel cells with a resin substrate film having a specific elastic modulus and thickness range, combined with a heat seal layer, ensuring uniformity and improved adhesion between separators.

Benefits of technology

The laminated body enhances the uniformity of distances between separators, improving the dimensional stability and handleability of fuel cell stacks.
