|1. (WO2018124039) FUEL CELL MANUFACTURING METHOD AND PROCESSING DEVICE|
|Applicants:||HONDA MOTOR CO., LTD.
|Title:||FUEL CELL MANUFACTURING METHOD AND PROCESSING DEVICE|
Provided is a fuel cell manufacturing method which makes it possible to easily form an inter-connector portion electrically connecting adjacent unit cells in a planar arrangement-type fuel cell. An inter-connector portion (30) is formed through a localized heating process in which an electrolyte film (12) is locally heated to carbonize a proton-conducting resin. The localized heating process includes a first heating step of heating a part of the electrolyte film (12) to a temperature not higher than a first temperature at a first temperature-increase rate or smaller, and a second heating step, after the first heating step, of heating the part of the electrolyte film (12) to not less than a second temperature higher than the first temperature, at a temperature-increase rate greater than the first temperature-increase rate.
