Tuning electrochemical and transport processes to achieve extreme performance and efficiency in solid oxide cells

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_x and GDC nanocatalysts pushes the limits of cell polarizations, exceeding fuel cell power density ∼3 W cm⁻² and electrolysis current density ∼4 A cm⁻².
