Processing Ceramic Proton Conductor Membranes for Use in Steam Electrolysis.

Steam electrolysis constitutes a prospective technology for industrial-scale hydrogen production. The use of ceramic proton-conducting electrolytes is a beneficial option for lowering the operating temperature. However, a significant challenge with this type of electrolyte has been upscaling robust planar type devices.

Direction observation of the grain boundary segregation in molybdenum substituted lanthanum tungstate membranes.

Molybdenum substituted lanthanum tungstate membranes (LWO-Mo) offer a good alternative for the separation of hydrogen from gas mixtures. During several essential steps of the membrane processing, an intensive employment of ZrO milling balls is usually inevitable. However, how these milling balls affect the final LWO-Mo membranes, is still largely unknown.
