Understanding High-Temperature Electrolysis

ECS Transactions, vol. 103, pp. 487–492

Abstract

Electrolysis is the technology, which provides the key for sector coupling. It enables the conversion of renewable energy to material value generation. Obviously, it is of utmost importance, that the energy is used in the most efficient way. High-temperature electrolysis on solid oxide cells provides high efficiency combined with the possibility to convert both water (H2O) and carbon dioxide (CO2) to hydrogen (H2) and carbon monoxide (CO) at the same time. In this contribution, we show the summary and conclusions of multiple investigations of the high-temperature electrolysis. A series of detailed analysis has been performed using current-voltage characteristics (IV curves), electrochemical impedance spectroscopy (EIS), and theoretical calculations.
