Abstract
Official abstract text for this publication.
A polymer electrolyte fuel cell of the present invention includes a membrane-electrode assembly ( 5 ) and separators ( 6 A and 6 B). Each of the electrodes ( 4 A and 4 B) includes a catalyst layer ( 2 A, 2 B) and a gas diffusion layer ( 3 A, 3 B). One main surface of the catalyst layer contacts the polymer electrolyte membrane ( 1 ). The separator ( 6 A) includes a peripheral portion ( 16 A) and a portion ( 26 A) other than the peripheral portion. The peripheral portion ( 16 A) of the separator ( 6 A) is formed in an annular shape when viewed from a thickness direction of the separator ( 6 A) and is a region including a portion located on an inner side of the outer periphery of the separator ( 6 A). The separator ( 6 A) is configured such that a porosity of the peripheral portion ( 16 A) is higher than that of the portion ( 26 A) other than the peripheral portion.
First claim
Opening claim text (preview).
The invention claimed is: 1. A polymer electrolyte fuel cell comprising: a membrane-electrode assembly including a polymer electrolyte membrane and a pair of electrodes sandwiching the polymer electrolyte membrane, the pair of electrodes including a first electrode and a second electrode; and a pair of separators each having a plate shape and electrical conductivity, the pair of separators including a first separator and a second separator, wherein: at least the first separat…
