Abstract
Official abstract text for this publication.
A support according to an embodiment includes fibers. A first arithmetic mean roughness of the fibers observed from in-plane direction of the support is 7 [μm] or more and 40 [μm] or less. A first sampling length of the first arithmetic mean roughness is one fifth of an average diameter of the fibers observed from the in-plane direction of the support.
First claim
Opening claim text (preview).
What is claimed is: 1 . A support comprising: fibers, wherein a first arithmetic mean roughness of the fibers observed from in-plane direction of the support is 7 [μm] or more and 40 [μm] or less, and a first sampling length of the first arithmetic mean roughness is one fifth of an average diameter of the fibers observed from the in-plane direction of the support. 2 . The support according to claim 1 , wherein first arithmetic mean roughness is 15 [μm] or more and 30 [μm] or less. 3 . The support according to claim 1 , wherein a second arithmetic mean roughness of the fibers observed from lateral directions of the support is 10 [μm] or more and 30 [μm] or less, and a second sampling length of the second arithmetic mean roughness is one fifth of an average diameter of the fibers observed from the lateral directions of the support. 4 . The support according to claim 1 , wherein a third arithmetic mean roughness of the fibers observed from lateral directions of the support is 5 [μm] or more and 10 [μm] or less, and a third sampling length of the third arithmetic mean roughness is one half of an average diameter of the fibers observed from the lateral directions of the support. 5 . The support according to claim 1 , wherein the support includes fibers of valve metal. 6 . The support according to claim 1 , wherein the support includes fibers of titanium. 7 . The support according to claim 1 , a diameter of the fibers is 1 [μm] or more and 500 [μm] or less. 8 . An electrode comprising: the support according to claim 1 ; and a catalyst layer. 9 . A membrane electrolyte assembly comprising: the electrode according to claim 8 ; and an electrolyte membrane. 10 . An electrochemical cell comprising: the membrane electrolyte assembly according to claim 9 . 11 . A stack comprising: the membrane electrolyte assembly according to claim 9 . 12 . A stack comprising: the electrochemical cell according to claim 10 . 13 . An electrolyzer comprising: the stack according to claim 11 . 14 . An electrolyzer comprising: the stack according to claim 12 .
