Abstract

Modifications of operational regimes for solid oxide electrolyzer cell (SOEC) devices for hydrogen production are discussed. It is shown that applying alternating current voltage pulses at a certain frequency range to SOECs could reduce oxygen delamination degradation in these devices and significantly increase their lifetime. This operational scheme provides possibility to increase longevity of SOEC devices required for their use in commercial hydrogen production processes, without any significant modification of used materials and/or cell design.
