ABSTRACT:
A fuel cell is disclosed having a separator that can minimize damage to a membrane electrode assembly. The separator advantageously has a groove therein approximately positioned over an outer edge of an electrode of the fuel cell to reduce any pressure between the separator and the outer edge of the electrode upon assembly and during use thereafter.
