Summary:

In addition to the purely design aspect of utilization of newprinciples of functioning the searching of ways for processintensification in the life support electrochemical systems islinked to the study of self-organization and stability of theexisting working processes in the modes of fluctuations ortransients.Stability analysis of the electrochemical systems (EChS) andestablishment of causes of instability outsetting are usually basedon the small parameter method or on investigation of eigenvalues ofthe characteristic equation of mass transfer assuming immobility ofthe diffusion layer.The system of water purification from the atmospheric moisturecondensate of the long-life orbital stations was chosen as atypical object of study.The broad spectrum of admixtures (up to 400 names) and durationof the autonomous existence put forward a problem of the complexevaluation of the operational mode stability as well as assessmentof the EChS self-organization for the known energy constraints.The proposed approach uncovers the instability mechanisms andexposes the ways of their elimination when studying the interactionmechanism of transfer processes.In the case of boundary perturbations the energy estimationdefines their suppression by the self-regulating processes.The integral dissipation function method allows to estimateenergy expenses on bringing system back to the original state anddefine acceptability of the proposed operational mode
