Abstract

This invention provides arrays of independently acting compliant electrical contacts within a fuel cell. These contacts maintain electrical contact between a plate and the adjacent membrane electrode assembly, and provide substantially uniform internal pressure distribution and substantially uniform electrical contact. In one embodiment, the electrical contacts are springs, which can take a variety of forms.
