Short Stack Kit – Short Stack Kit with Compression Furnace

The Nexceris Short-Stack Kit provides a hands-on, easy to assemble stack solution for researchers developing their own next-generation SOFC and SOEC technologies. Its modular, compact design and advanced materials make it an ideal choice for accelerating the commercialization of sustainable energy innovations.

Key Features and Benefits:

• Enhanced Reproducibility – Uses Nexceris’ NextCell™ platform for consistent and reliable results, compare across different button cell, single cell and stack platforms.

• Compact & Modular Design – Supports 1-5 cell configurations, fits in most standard testing furnaces, requires a low (45lbs) deadweight.

• Quick Reversible Operation – Switch between SOFC and SOEC modes in under 15 minutes, stack is optimized to run in any mode of operation.

• Advanced Sealing Technology – Glass-ceramic composite seals ensure high-temperature durability and low CTE mismatch between the stack components.

• High-Performance Materials – Ferritic interconnects with Chromlock® coatings provide low Cr diffusion and excellent conductivity. Ask Nexceris for this technology.

• Efficient Testing & Validation – Accelerates materials research with easy integration into existing setups and at your own lab without the need of any expert installation. Kit comes with everything you need to build an advanced stack.
