Abstract
A laminar electrical contact for fuel cells is disclosed. By optimizing the contact area and pressure between a separator plate and a membrane electrode assembly, the lamina of the present invention improves fuel cell efficiency and performance. The lamina may rest upon compliant members or springs that push the lamina into the adjoining membrane electrode assembly, thereby assuring continuous and robust electrical contact between the separator plate and the membrane electrode assembly.
