Abstract

Liquid metal anode (LMA) solid oxide fuel cells (SOFCs) are a promising type of high temperature fuel cell suitable for the direct oxidation of gaseous or solid fuels in the bulk of liquid metal. Depending upon the operating conditions, they can be run in four different modes. In the present study, concerning the mechanism of reaction and species transport in LMA SOFCs, the oxidation of fuel (H2) in the bulk of a liquid tin anode has been investigated via operation in so-called Chemical - Electrochemical mode (CE mode) and Electrochemical - Chemical (EC) modes. Theoretical considerations to be applied in the modelling of the obtained experimental data regarding the dissolution of hydrogen in a molten tin anode and its oxidation with oxygen dissolved in liquid tin followed by anodic oxygen injection in mode CE are also discussed.
