By using proton-conducting electrolyte, the SOEC operating temperature can be reduced from over 800oC to below 600oC due to higher conductivity and lower activation energy. Technical barriers associated with the conventional oxygen-ion conducting SOECs, such as hydrogen separation from water, oxidation of steam electrode, and instability of oxygen electrode, can be largely mitigated. In this report, an intermediate temperature (500-600oC) electrolysis technology was developed where a novel proton-conductor and a triple-conducting oxide were used as the electrolyte and oxygen electrode, respectively. The electrolysis cell demonstrated excellent performance at intermediate temperatures, promising a new prospective for next-generation steam electrolysis.}, doi = {10.1149/08009.0167ecst}, url = {http://ecst.ecsdl.org/content/80/9/167.short}, author = {Dong Ding and Wei Wu and Ting He} } @article {1153, title = {Chalkboard 2 - How to Make Clean Hydrogen}, journal = {The Electrochemical Society Interface}, volume = {30}, year = {2021}, month = {dec}, pages = {49{\textendash}56}, abstract = {Clean hydrogen is a carbon-free energy carrier that can be produced from water and sustainable energy sources such as wind, solar, and nuclear.

Published on May 21st, 2019. Proton conducting oxide electrolyte materials could potentially lower the operating temperature of metal-supported solid oxide cells (MS-SOCs) to the intermediate range 400 to 600\ {\textdegree}C. The porous metal substrate provides the advantages of MS-SOCs such as high thermal and redox cycling tolerance, low-cost of structural materials, and mechanical ruggedness. In this work, the viability of co-sintering fabrication of metal-supported proton conducting solid oxide cells using BaZr1-x-yCexYyO3-δ (BZCY) is investigated. BZCY ceramics are sintered at 1450\ {\textdegree}C in reducing environment alone and supported on FeCr alloy metal support, and key characteristics such as Ba loss, sintering behavior, and chemical compatibility with metal support are determined. Critical challenges are identified for this fabrication approach, including: Contamination of the electrolyte with Si and Cr from the metal support, incomplete electrolyte sintering, and evaporation of electrolyte constituents. Various approaches to overcome these limitations are proposed, and preliminary assessment indicates that the use of barrier layers, low-Si-content stainless steel, and sintering aids warrant further development.

In article number 1800360, Dong Ding and co-workers report a self-architectured ultraporous 3D electrode for steam electrolysis at intermediate temperatures. The proton-conducting electrolysis cell using this steam electrode demonstrates highly efficient and durable hydrogen production below 600 {\textdegree}C, which is attributed to improved mass transfer and increased active reaction area, as well as the electrode reconstruction under operation conditions.
