Abstract
Highly efficient electrolyzers will be a key component of our future energy infrastructure. An intermediate operating temperature between 100 °C and 250 °C could offer increased efficiency and advantages in system design. However, electrolytes for electrolysis in this temperature range have received little attention so far. In this study, layered double hydroxides are demonstrated as solid-state electrolytes for water splitting at an intermediate temperature of 146 °C and a remarkable gain in efficiency is observed with increasing temperature. This opens new opportunities for electrolyzers and other electrochemical devices in the promising intermediate temperature range.
