Title:
ELASTOMERIC COMPRESSION PAD WITH BOTH EXPANSION AND ELECTRICAL PATHWAYS
Document Type and Number:
WIPO Patent Application WO1994013860
Kind Code:
A3
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. An elastomeric compression pad comprised of an oil adsorbent sheet surrounding an elastomeric material with expansion pathways and electrical pathways, that utilize a conductive powder and elastomeric binder compensates for component dimensional variations, improves inter-cell conductivity, and allows high pressure operation up to about 3,000 psig.
