Definitions

  • One of the hydrogen production methods is the electrolysis of water. If surplus electricity from renewable energy is used to electrolyze water, electricity can be converted into hydrogen energy without emitting carbon dioxide. Furthermore, depending on the storage method, hydrogen can be transported by tank truck or tanker, and can be supplied to the required place at the required time, so water electrolysis has high potential as a tool for power storage.
  • the catalyst layer-attached electrolyte membrane of the present invention has the following configuration. i.e. A catalyst layer-attached electrolyte membrane comprising catalyst layers on both surfaces of the electrolyte membrane laminate, wherein a first catalyst layer is provided on a first main surface side of the first electrolyte membrane of the electrolyte membrane laminate; 2.
