“…The LSM plasma coated samples have mass gains in oxygen similar to the ones reported for oxidation in air. In other studies[5,7], 1000 hour oxidation experiments performed in oxygen at 850°C resulted in mass gain of approximately 0.85 mg cm -2 for LSM plasma coated Crofer 22 APU and 0.60 mg cm -2 for a similar dual layer coating also on Crofer 22 APU. FromFigure 3it is clear that protective coatings offer enhanced corrosion protection and the dual layer coating seems effective in reducing the corrosion rate[7][8][9][10].…”

Oxidation rates of ferritic steels used as interconnector plates in Solid Oxide Electrolysis Stacks are of concern as they may be determining for the life time of the technology. In this study oxidation experiments were carried out for up to 1000 hours in hydrogen-side and oxygen-side simulated atmospheres at 800°C. Four commercially available alloys: Crofer 22 APU, Crofer 22 H, AL29-4, E-Brite were characterized in humidified hydrogen. One alloy, Crofer 22 APU was also characterized in pure oxygen both in the as-prepared state and after application of a protective coating. Best corrosion resistance in humidified hydrogen atmosphere was observed for Crofer 22 APU and Crofer 22 H alloys. Corrosion rates for Crofer 22 APU measured in humidified hydrogen are similar to the corrosion rates measured in air. Both coatings of plasma sprayed LSM and dual layer coatings (Co3O4/LSM-Co3O4) applied by wet spraying were found to reduce corrosion rates in pure oxygen significantly.

“…On the other hand, nearly all the references cited deal with simple optimisation experiments; whereas papers dealing with a fundamental background do not occur frequently [126]. Different characteristics are found with solid oxide fuel cells (SOFC) [138][139][140][141][142][143]. Not very far from classic experiments are fuel cells with polymer electrolyte [127][128][129][130][131][132], preferably proton exchange membrane fuel cells (PEMFC) [128][129][130][131][132].…”

Surprisingly, a large number of important topics in electrochemistry is not covered by up-to-date monographs and series on the market, some topics are even not covered at all. The series Monographs in Electrochemistry fills this gap by publishing indepth monographs written by experienced and distinguished electrochemists, covering both theory and applications. The focus is set on existing as well as emerging methods for researchers, engineers, and practitioners active in the many and often interdisciplinary fields, where electrochemistry plays a key role. These fields will range -among others -from analytical and environmental sciences to sensors, materials sciences and biochemical research.

“…Bonding is established via an interdiffusion of elements. Iron, chromium, manganese and cobalt have relatively high mobility and diffusion rates, and they react at these temperatures [30,31]. This leads to change in chemical composition of the oxygen electrode at its contact zone with the metal.…”
