Hot‐Roll‐Milled Electrolyte Structures for Molten Carbonate Fuel Cells

Abstract

Hot‐roll‐milling has been evaluated as a technique for preparing porous matrices for use as a molten carbonate fuel cell electrolyte matrix. This technique produces reliable electrolyte structures with the following characteristics: controlled pore size distribution, uniform thickness, ease of handling, and ability to be impregnated with the alkali carbonate without fracture. In‐cell testing of these structures has resulted in improved cell performance over state‐of‐the‐art hot‐pressed structures.
