Abstract
Official abstract text for this publication.
A fuel cell unit of a fuel cell contains a first membrane electrode assembly having a frame portion on an outer circumference thereof, a first separator, a second membrane electrode assembly having a frame portion on an outer circumference thereof, a second separator, and a third separator. A plurality of resin pins are formed integrally on the frame portion of the first membrane electrode assembly. The resin pins are integrally inserted into holes in the first separator, holes in the second membrane electrode assembly, holes in the second separator, and holes in the third separator.
First claim
Opening claim text (preview).
What is claimed is: 1. A fuel cell unit formed by stacking a rectangular membrane electrode assembly and a rectangular metal separator together, the membrane electrode assembly comprising a pair of electrodes and an electrolyte membrane interposed between the electrodes, a picture-frame-like resin frame being formed on an outer circumference of the membrane electrode assembly, wherein: the membrane electrode assembly has a plurality of fastening members situated exclusively at cen…
