The planar-tube Solid Oxide Cell (SOC) stack utilizes large-area hollow planar tube cells as its fundamental units, overcoming the limitations of conventional SOFC and SOEC stacks in fuel flexibility, durability, and operational complexity. It represents a key technology for high-temperature fuel cells and high-efficiency electrolysis systems.
Large-Area Hollow Planar Tube Design
Each individual cell features a hollow planar tube structure, providing a large reaction area and higher current-carrying capacity per stack.
The hollow design ensures uniform gas flow, optimizes reaction distribution, reduces local overpotentials, and improves overall stack efficiency.
Material Optimization
Electrolytes are made of high-conductivity ceramics (e.g., YSZ), while electrodes use high-durability composite materials to ensure stable operation at high temperatures.
Interfaces between electrodes and electrolytes are microstructurally optimized to enhance electron and ion transport, increasing electrochemical reaction efficiency.
Modular Stack Design
Planar-tube units can be flexibly assembled into stacks of different capacities, supporting MW-scale stationary power generation or large-scale hydrogen production.
Modular design simplifies maintenance and replacement, improving on-site operability.

Wide Fuel Flexibility
Compatible with methanol, methane, propane, ammonia, and other fuels without requiring complex fuel pretreatment systems.
High Robustness and Long Lifespan
The stack’s robust structure and excellent thermal cycling resistance make it ideal for mobile machinery, industrial power generation, and large-scale electrolysis applications.
Dual-Mode Compatibility (SOFC & SOEC)
Optimized electrode materials and stack design allow stable operation under both fuel cell (SOFC) and high-temperature steam electrolysis (SOEC) modes.
User-Friendly Operation
Compact structure and high system integration simplify installation, operation, and maintenance, reducing operational complexity and costs.
Mobile Power Systems: Suitable for applications requiring high durability and power density, such as mobile machinery or transportation.
Stationary Power Generation: Scalable to MW-level systems for industrial parks, data centers, or other high-demand facilities.
Large-Scale Hydrogen Production: In SOEC mode, the planar-tube SOC stack enables high-temperature, high-efficiency hydrogen generation, which can be coupled with industrial waste heat for green hydrogen production.
