ABSTRACT:
A UEA for a fuel cell having an active region and a feed region is provided. The UEA includes an electrolyte membrane disposed between a pair of electrodes. The electrolyte membrane and the pair of electrodes is further disposed between a pair of DM. The electrolyte membrane, the pair of electrodes, and the DM are configured to be disposed at the active region of the fuel cell. A barrier film coupled to the electrolyte membrane is configured to be disposed at the feed region of the fuel cell. The dimensions of the electrolyte membrane are thereby optimized. A fuel cell having the UEA, and a fuel cell stack formed from a plurality of the fuel cells, is also provided.
