Ammonia-fed reversible protonic ceramic fuel cells with Ru-based catalyst

Abstract

Ammonia-fed protonic ceramic fuel cells could be a more sustainable alternative than their hydrogen-fed counterparts. In this work, the authors couple an reversible ammonia catalyst with a protonic ceramic electrochemical cell, enabling cracking of ammonia into H2 and N2 for fuel-cell mode operation, as well as synthesis of ammonia from H2O and N2 in electrolysis mode operation.
