Solid Oxide Cell Technology

A unified platform for hydrogen production and power generation

VoltaCera develops solid oxide cell technologies for both electrolysis (SOEC) and power generation (SOFC), based on a shared electrolyte-supported ceramic cell platform.

Both technologies are built on an electrolyte-supported ceramic cell (ESC) platform, enabling:

• Scalable manufacturing
• High durability and long lifetime
• Flexible deployment across energy applications

Our unified platform allows partners to develop hydrogen, power, and e-fuel systems using a common, proven cell architecture.

Electrolyte-Supported Ceramic Cell Platform

At the core of VoltaCera’s technology is an electrolyte-supported ceramic cell (ESC) architecture designed for long-term durability and scalable manufacturing.

Built for long lifetime operation

Electrolyte-supported cells offer inherent structural robustness compared with electrode-supported designs.

Key advantages:

• Mechanically robust electrolyte backbone
• Stable electrode-electrolyte interfaces
  
• Reduced degradation during long-term operation
• Improved tolerance to thermal cycling

ESC architecture enables reliable multi-year operation in demanding industrial environments.

Optimized for scalable manufacturing

• Controlled electrolyte thickness and composition
• High reproducibility across large batch production
  
• Cell designs compatible with both SOEC and SOFC operation

SOEC Technology for Hydrogen and E-fuel Production

VoltaCera’s SOEC technology enables high-efficiency hydrogen and syngas production using high-temperature steam electrolysis.

Our ESC platform provides key advantages for long-term SOEC operation.

Why ESC for SOEC?

High-temperature electrolysis requires cells that can operate reliably under demanding conditions.

The ESC architecture offers:

• Enhanced durability under electrolysis conditions
• Improved resistance to redox and thermal cycling
• Stable long-term performance at high current density
• Reduced degradation over thousands of operating hours

This makes ESC particularly well suited for industrial-scale hydrogen production.

Applications

• Green or Pink hydrogen production
• Co-electrolysis for syngas (H₂ + CO) production
  
• E-fuel and synthetic fuel pathways

SOFC Technology for Efficient Power Generation

VoltaCera’s SOFC technology converts hydrogen and hydrocarbon fuels directly into electricity with high efficiency and low emissions.

Built on the same ESC platform, our cells offer reliable long-term operation for distributed power applications.

Applications

• Distributed power generation
• Combined heat and power (CHP) systems
  
• Backup and off-grid power solutions
• Long-range mobility applications

Technology Built for Real-World Deployment

Our technology is developed with a strong focus on real-world deployment and manufacturability.

• Designed for manufacturability, not just lab performance
• Rapid design iteration based on customer requirements
  
• Stable domestic supply chain and technical support in Korea
• Close collaboration with stack and system partners
