<p>An electrochemical fuel cell stack includes a plurality of fuel cell assemblies interposed between a pair of end plate assemblies (115, 120). The mechanism for securing the stack in its compressed, assembled state includes at least one compression band (130) which circumscribes the end plate assemblies and interposed fuel cell assemblies of the stack. Preferably, at least one of the end plate assemblies comprises a resilient member which cooperates with each compression band to urge the first end plate assembly toward the second end plate assembly, thereby applying compressive force to the fuel cell assemblies to promote sealing and electrical contact between the layers forming the fuel cell stack.</p> |
