A traditional composite cathode for proton-conducting solid oxide fuel cells (H-SOFCs) is typically obtained by mixing materials and proton conducting electrolyte of BaCe0.7Y0.2Zr0.1O3–? (BZCY), providing chemical thermal compatibility with the electrolyte. Here, a series triple-conducing cobalt-free iron-based perovskites as cathodes H-SOFCs reported. Specifically, BaCexFe1–xO3–? (x = 0.36, 0....

Highly efficient and chemically compatible LnxSr1-xCoO3-delta (Ln = La, Sm, Gd, ...)/Co3O4 electrocatalysts for oxygen reduction reaction are presented and the very low cathode polarization resistances and excellent performances implied their promising application for developing intermediate-temperature solid oxide fuel cells (SOFCs), as well as potential application for oxygen separation membr...

Solid oxide fuel cell (SOFC) is a promising alternative energy source, with its advantages of high operating efficiency, fuel flexibility, low emissions and relatively low cost. However, there are several challenges concerning the SOFC research. Little is known about the complex interfacial electrochemistry and thermochemistry, and it is also difficult to diagnose problems and optimize cell per...

Ammonia produced using renewable hydrogen is being viewed as a promising media for the export of energy from locations rich in sources. Solid oxide fuel cells (SOFCs) are efficient devices converting such exported ammonia back into electricity at point use; however, investigations on materials and operating regimes direct fuelled SOFCs limited. In this work, we evaluated SOFC performance with S...

Solid oxide fuel cells (SOFCs) can generate electricity through an electrochemical conversion of the chemical energy fuels including hydrogen, hydrocarbons, and biogas because high operation temperatures. Ammonia has recently been considered as a promising hydrogen carrier that is relatively convenient to store transport be decomposed into nitrogen with no carbon emission via catalytic cracking...

Proton-exchange membrane (PEM) fuel cells are being developed for both automotive (motive and/or auxiliary) and stationary (residential) power applications. Solid oxide fuel cells (SOFCs) also are being pursued for a number of power generation applications, including stationary (residential and utility), and automotive (auxiliary) power sources. For both of these types of fuel cells, the use of...

Micro-tubular solid oxide fuel cells (µT-SOFCs) are suited to a broad range of applications with power demands ranging from few watts several hundred watts. µT-SOFCs possess inherently favourable characteristics over alternate configurations such as high thermo-mechanical stability, volumetric density and rapid start-up times, lending them particular value for use in portable applications. Effi...
