Influence of the geometry of gas channels on the current balance in the operation of solid oxide electrolyzers

Optimization of the design of solid oxide electrolyzers is promising for the development of both energy and industry in general. Therefore, research in the sphere of improving the efficiency and reliability of electrolyzers is conducted by scientists around the world. In the paper, the authors consider a change in the design parameters of interconnectors for a solid oxide electrolyzer, which makes it possible to assess the impact of the design on the operating parameters of the existing and newly designed equipment. In particular, special attention is paid to studying the effect of the trajectory of gas channels on the current balance of an electrochemical device. Based on modeling for a solid oxide electrolyzer of a planar design, the authors determine relation between the geometric dimensions of the elements when changing the trajectory of the gas channels of the interconnector and voltage losses during its operation.
