Title:
JUNCTION STRUCTURE
Document Type and Number:
Japanese Patent JP2022134383
Kind Code:
A
Abstract:
To provide a junction structure capable of securing sealability between a support frame and a membrane electrode assembly even when different deformations occur in the support frame and the membrane electrode assembly.SOLUTION: A junction structure joins: a membrane electrode assembly 20; and a support frame 19 which includes a support face 23 supporting a peripheral part of the membrane electrode assembly 20 and on which the membrane electrode assembly 20 is laminated. The junction structure comprises: an elastic body 21 disposed at least partially between the membrane electrode assembly 20 and the support face 23; a first junction 24 to join the membrane electrode assembly 20 and the elastic body 21; and a second junction 25 to join the support face 23 and the electric body 21. Positions of the first junction 24 and the second junction 25 deviate mutually in a thickness direction Z of the support frame 19 which is a direction of lamination of the membrane electrode assembly 20 and the support frame 19.SELECTED DRAWING: Figure 4
