Segmented sealing frames reduce maintenance costs while maintaining reliability through vulcanized gaskets.
Fatty acid potassium or sodium in the rubber composition improves mold releasability without compromising adhesiveness or dimensional accuracy.
Removing B2O3 prevents electrode contamination while maintaining electrical insulation in solid oxide fuel cell seals.
Unexpanded vermiculite within the refractory matrix expands by 5 to 50 percent at 1200°F, compensating for binder shrinkage to maintain sealing integrity.
An elastomeric seal circumscribes the active area of a framed membrane electrode assembly using flow-processable material injected through a frame through-hole.
Projections on fuel cell separators compress fiber sheets to reduce microvoids, preventing hydrogen and air leakage through the seal.
