Abstract
Accumulated dimensional variations in fuel cells and electrolysis cell assemblies can reduce the efficiency of the assembly and provide leakage paths for fuel and oxidant. A metal compression pad comprised of a metal having an elastic strain of about 3% to about 40% at about 2,500 psig can compensate for component dimensional variations and improve inter-cell conductivity at pressures up to and exceeding about 10,000 psig.
