Journal of Power of Technologies
EN This work considers electronic conductance in solid oxide fuel cells and consequences of its existence. Various types of electrolyte are analyzed. The voltage characteristics of cells show differences between a theoretical maximum circuit voltage and open circuit voltage (OCV). A relationship is ass[...]

EN The article presents a comparative analysis of the time constants of the main processes in the SOFC. The analysis was used to determine those processes most relevant to the modeling of an energy system comprising a fuel cell. The hybrid system, in addition to the fuel cell, has other devices (such a[...]
