Abstract
An electrochemical device subassembly is provided that includes a membrane electrode assembly and a gasket. The membrane electrode assembly includes an electrolyte membrane having a first major surface, a second major surface opposite the first major surface, and a peripheral edge. The gasket is disposed adjacent the first major surface of the electrolyte membrane at the peripheral edge, and has a plurality of replicated structures that extend greater than about 250 micrometers from a surface of the gasket.
