Abstract
A new SOC that utilizes a very thin GDC/YSZ bi-layer electrolyte, support with enhanced porosity, and electrode surface modification <italic>via</italic> PrO<sub>x</sub> and GDC nanocatalysts pushes the limits of cell polarizations, exceeding fuel cell power density ∼3 W cm<sup>−2</sup> and electrolysis current density ∼4 A cm<sup>−2</sup>.
