Abstract
A manufacturing method of fuel cell and a fuel cell are provided. The manufacturing method of fuel cell includes a first slit formation process in which first slits are formed in a first electrode, an electrolyte membrane lamination process in which an electrolyte membrane is laminated on the first electrode, an IC formation process in which interconnector portions are formed on the electrolyte membrane, a second slit formation process in which second slits are formed in a second electrode, a second electrode lamination process in which the second electrode is laminated on the electrolyte membrane, and a side edge portion removal process in which side edge portions of the first electrode and the second electrode are removed to divide the first electrode into a plurality of parts via the first slits and to divide the second electrode into a plurality of parts via the second slits.
