Abstract
A fuel cell includes a membrane electrode assembly, and first and second separators. A first insulating bushing is attached to a first positioning hole of a first separator, and a second insulating bushing is attached to a second positioning hole of the second separator. An inner wall of the first insulating bushing is fitted to an outer wall of the second insulating bushing for positioning the first and second separators such that the first and second separators are insulated from each other.
