Abstract
An electrochemical fuel cell assembly with compliant compression mechanism includes a first plate, a second plate, and at least one membrane electrode assembly disposed between the first and second plates. Compliant compression members, such as twisted wire springs or ribbon springs, extend between the first and second plates such that the compression members urge the first plate toward said second plate to compress each membrane electrode assembly interposed between the plates. In operation, compressive force is applied by the compression members to each membrane electrode assembly to maintain electrical conductivity.
