MATRIX MATERIAL FOR MOLTEN CARBONATE FUEL CELL

摘要

A matrix material for a molten carbonate fuel cell is described which is flexible, pliable and has rubber-like compliance at room temperature. The matrix has three components comprising fine inert particulate material, larger crack attenuating ceramic particulate material, and an organic polymeric binder. A process of assembling a molten carbonate fuel cell utilizing the compliant matrix material is also described. The compliant matrix material is inserted into a molten carbonate fuel cell stack utilizing fuel cell anodes with sufficient porosity to contain excess electrolyte. The fuel cell is heated up to a temperature sufficient to remove the polymer binder and cause a portion of the electrolyte material present in the anode to wick into the matrix to substantially fill it completely.
