In the molten carbonate fuel cell, the electrolyte distribution in the electrode is one of the major factors affecting cell performance. An electrolyte distribution model was developed in consideration of the electrode's wetting properties and die pore size distribution within the electrode. Because wettability data, e.g., contact angles, are required for model calculations, the meniscus; heights of (Li/K)CO3 and (Li/Na)CO3 on Ni were measured under various anode gas conditions, and contact angles were derived.
