Abstract

The paper deals with some questions concerning carbonization and decarbonization of alkaline electrolyte in matrix fuel cell (FC). It is shown that there is an equilibrium ultimate level of carbonization that depends on CO2 content in gases delivered into FC and FC electric loading. Electrolyte decarbonization takes place at the increase of FC load current with CO2 emission at hydrogen electrode end. The possible mechanisms of electrolyte carbonization and decarbonization are suggested.
