Determination of contact angle in porous molten-carbonate fuel-cell electrodes

摘要: A method of capillary rise (gravimetrically measured) has been investigated for determination the electrolyte contact angle in porous electrodes molten-carbonate fuel cell. The experiments were conducted on LiCoO{sub 2} air, at different temperatures (555 to 740 C), monitor influence temperature angle. results indicate that decreases with increasing temperature. obtained good reproducibility, and shows promise as a useful tool characterization wetting phenomena fuel-cell electrodes, making it possible study manufactured, under electrochemical conditions. wetting-in was characterized also by post-test measurements, found front (i.e., from no fully flooded), extends over several millimeters.
