The aim of this work is to study whether the effects of electrolyte evaporation in long term operation of MCFCs can be accelerated at button cell level due to the increased rate of evaporation in the open-chamber configuration. This study is being carried out with several trials: the first trial aims to generate a benchmark of performance at button cell level, i.e. with accelerated electrolyte evaporation, at reference operating conditions, carrying out regular polarization curves and EIS until the performance degrades below a predefined level. The second trial aims to compensate the evaporation of electrolyte from the button cell by periodically adding carbonate and maintain a constant performance for the length of time that the first button cell (without carbonate addition) achieved. Once the isolated effect of electrolyte evaporation has been thus quantified, successive trials can be set up to superimpose other degradation and evaluate their interaction with the mechanism of electrolyte evaporation.
