A caulk composition includes: at least one powder component and at least one binder component. The powder component is a ball-milled powder component comprising ceria, zirconia, alumina, or a combination thereof. The powder component is a heat-treated powder component that has been heated to a temperature of at least 1500 C. The powder component is present in a concentration range of 65 wt % to 75 wt % of the caulk composition. The powder component has a particle size distribution of 95% less than 25 m and 90% greater than 1 m. The binder component is present in a concentration range of 25 wt % to 35 wt % of the caulk composition.

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 m and 90% greater than 1 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.

The present invention is concerned with improved swirl burners, particularly, but not limited to, swirl burners used in fuel cell systems.

Molten carbonate fuel cell structures are provided that include a structural mesh support layer at the interface between the surface of the cathode and the cathode current collector. The structural mesh layer can have a mesh open area of 25% to 45%. In addition to providing structural support, the structural mesh layer can reduce or minimize ohmic resistance at the interface between the cathode and the cathode current collector.
