Abstract
A fuel cell manufacturing method capable of easily forming an interconnector part electrically connecting adjacent unit cells in a planar array fuel cell is provided. The interconnector part () is formed through a local heating process of carbonizing a proton conductive resin by locally heating an electrolyte membrane (). The local heating process includes: a first heating step of heating a part of the electrolyte membrane () to a temperature equal to or less than a first temperature at a first temperature increase rate or less; and a second heating step of heating the part of the electrolyte membrane () to a temperature equal to or greater than a second temperature higher than the first temperature at a temperature increase rate greater than the first temperature increase rate, after the first heating step.
