Solid oxide fuel cells (SOFCs) are promising and rugged solid-state power sources that can directly electrochemically convert the chemical energy into electric power. Direct-hydrocarbon SOFCs eliminate external reformers; thus, system is significantly simplified capital cost reduced. comprise cathode, electrolyte, anode, of which anode paramount importance as its catalytic activity stability ke...

Degradation of solid oxide electrolysis cells (SOECs) is probably the biggest concern in the field of high temperature steam electrolysis (HTSE). Anode supported, YSZ-based microtubular solid oxide fuel cells (SOFC) have been tested in fuel cell mode and also at high voltages (up to 2.8V) under electrolysis mode. At high steam conversion rates the cell voltage tends to saturate. Our hypothesis ...

Introduction The purpose of this project is to develop new understanding of the atomic-scale structure and dynamics of oxide ion conducting ceramic materials that are at the heart of solid oxide fuel cells (“SOFC’s”), with the aim of more effectively optimizing their performance, lowering operating temperatures, size, and costs. Given the high efficiencies of fuel cells and their likely central...
