PROBLEM TO BE SOLVED: To provide a method of manufacturing fuel cell-related parts which allows for reliable laser welding of closed circuit shape, while reducing the number of jig members constituting a welding jig device or the number of fixing members thereof.SOLUTION: In a first welding step, a separator 54 and a fuel electrode frame 56 are held between a first jig member 131 having a first opening 141 and a fixture member 133 and fixed in place, before welding is performed by irradiating a welding area in the first jig member 131 with laser L1 along the first opening 141. In a second welding step, a second jig member is attached to the fixture member 133 in place of the first jig member 131. In the welding area of closed circuit shape, the second jig member has a second opening for exposing at least a welding area other than that by the first opening 141. Welding is performed by irradiating the second jig member with laser L1 along the second opening. |
