Wet seal caulk with enhanced chemical resistance

Abstract:

A caulk composition includes at least one powder component and at least one binder component, such that the powder component has a particle size distribution in the range of 95% less than 25 .mu.m and 90% greater than 1 .mu.m. A molten carbonate fuel cell (MCFC) includes a fuel cell stack, a manifold, and the caulk composition disposed in between the fuel cell stack and the manifold.
