Abstract
Official abstract text for this publication.
A fuel battery 11 includes a cell laminated body 21 including lamination of a plurality of cells 20, a current-collecting plate 22 disposed at an end of the cell laminated body 21, the current-collecting plate being made of a metal material, and an anti-rust plate 23 disposed between the cell laminated body 21 and the current-collecting plate 22, the anti-rust plate being made of a metal material that is different from the metal material of the current-collecting plate 22. The anti-rust plate 23 includes a protrusion 31, and the current-collecting plate 22 includes a fitting hole 41, into which the protrusion 31 is fitted.
First claim
Opening claim text (preview).
What is claimed is: 1. A fuel battery, comprising a cell laminated body including lamination of a plurality of cells, a current-collecting plate disposed at an end of the cell laminated body, the current-collecting plate being made of a metal material, and an anti-rust plate disposed between the cell laminated body and the current-collecting plate, the anti-rust plate including a face that mates with a corresponding face of the current-collecting plate, and the anti-rust plate being made of a metal material having a different thermal expansion from the metal material of the current-collecting plate, wherein the anti-rust plate has a plurality of protrusions with sides extending perpendicular to the face of the anti-rust plate, each of the protrusions being disposed so as to protrude from the anti-rust plate toward the current-collecting plate, and the current-collecting plate includes a plurality of fitting holes, each of the fitting holes including internal sides extending perpendicular to the face of the current-collecting plate and being configured to receive a corresponding one of the protrusions, each of the fitting holes being disposed in the current-collecting plate at a respective position corresponding to a respective one of the protrusions of the anti-rust plate, and the protrusions are disposed so that a straight line connecting centers of the protrusions is substantially parallel to sides of the anti-rust plate in a planar view of the anti-rust plate.
