Abstract
Official abstract text for this publication.
A manufacturing method of a bipolar electrode includes the following (a) to (f). (a) A first carbon film is formed on the sheet-shaped support material. (b) A conductive resin layer is formed on the first carbon film. (c) A second carbon film is formed on the conductive resin layer. (d) A second electrode layer is formed on the second carbon film. (e) The support is separated from the first carbon coating. (f) A bipolar electrode is manufactured by forming a first electrode layer on the first carbon film.
First claim
Opening claim text (preview).
What is claimed is: 1 . A manufacturing method of a bipolar electrode, the manufacturing method comprising: (a) providing a first carbon film on a support material that is in a sheet form; (b) providing a conductive resin layer on the first carbon film; (c) providing a second carbon film on the conductive resin layer; (d) providing a second electrode layer on the second carbon film; (e) separating the support material from the first carbon film; and (f) manufacturing the bipolar electrode by providing a first electrode layer on the first carbon film, wherein the (d), the (e) and the (f) are performed in an order of the (d), the (e) and the (f). 2 . The manufacturing method according to claim 1 , wherein the support material includes a fluororesin. 3 . The manufacturing method according to claim 1 , wherein: the first electrode layer is a cathode layer; and the second electrode layer is an anode layer. 4 . A bipolar electrode comprising: a first electrode layer; a first carbon film; a conductive resin layer; a second carbon film; and a second electrode layer, in a thickness direction and in an order of the first electrode layer, the first carbon film, the conductive resin layer, the second carbon film, and the second electrode layer. 5 . The bipolar electrode according to claim 4 , wherein: area of the conductive resin layer is larger than each of the first electrode layer, the first carbon film, the second carbon film, and the second electrode layer; and the conductive resin layer extends to cover a side face of the first carbon film.
