To support the growing hydrogen generation market, Nexceris provides expertise and solutions for the development of Solid Oxide Electrolysis Cells (SOEC). In order to utilize as much of the electricity produced by nuclear, wind, solar, and other sources as possible, including storing that energy as hydrogen, SOEC is an important part of the Energy Plus Storage future.

Understanding the demand for these types of renewable sources, Nexceris is now developing technologies around SOEC. The research avenues in SOEC are similar to the ones for fuel cell, and the knowledge we have gained through SOFC research can be leveraged to push SOECs forward. As part of the effort Nexceris was recently awarded a project to research and produce advanced coatings to enhance the durability of SOEC stacks.

Here are some results from our R&D work in this area:

• Screened over 50 electrodes at part of development
• Cells achieve -2.0 A/cm² @ 1.4 V and 800 °C and 0.8 W/cm° @ 0.7 V
• Performance is further increased with thinner electrolyte or different cell platforms

fuelcellmaterials offers standard and tailored powders for SOEC applications including the fuel electrode, air electrode, and electrolyte, many of which are available in quantities ranging from 150 grams to industrial volumes of tons per year. All powders are produced at a high level of quality that ensures reproducible batches and come with complete documentation for characterization.

As a value added service to our customers, fuelcellmaterials can produce inks and pastes out of any of the powders we produce.

Electrolyte supported and anode supported SOEC cells are available in various sizes and shapes, including 25 mm diameter disks and in standard sizes up to 10 cm x 10 cm.

Test fixtures are supported by Nexceris’ experienced team and come with detailed operation manuals. fuelcellmaterials also offers all of the accessories needed to test properly, including contact mesh, seals, lead wires, contact pastes, and precious metal inks.
