In-House Manufacturing

From Powder to Cell — In-House Manufacturing

Vertically integrated solid oxide cell manufacturing enabling speed, consistency, and scalable production.

VoltaCera performs the entire solid oxide cell manufacturing process in-house — from raw powder preparation to final cell testing.

This vertically integrated approach ensures full process control, rapid iteration, and reliable scale-up from R&D to production.

Why Vertical Integration Matters

Many solid oxide cell developers rely on fragmented supply chains and outsourced process steps.
VoltaCera takes a different approach.

By controlling the entire manufacturing workflow internally, we can:

  • Optimize materials and processes simultaneously
  • Rapidly implement design changes
  • Ensure consistent quality across batches
  • Accelerate the transition from development to production

This integration shortens development cycles and reduces technical risk for our partners.

Our Manufacturing Workflow

Step 1 — Powder Preparation

High-purity ceramic powders are prepared and conditioned for electrode and electrolyte fabrication.

Key points:

  • Particle size control
  • Composition optimization
  • Slurry & paste formulation

Step 2 — Paste Mixing & Ink Formulation

Screen-printing pastes are engineered for stable coating, adhesion, and microstructure control.

Key points:

  • Rheology optimization
  • Repeatable ink preparation
  • Scalable formulation methods

Step 3 — Screen Printing & Layer Formation

Electrode and functional layers are deposited using scalable screen-printing processes.

Key points:

  • Multi-layer coating capability
  • Thickness & uniformity control
  • Stack-ready cell architecture

Step 4 — High-Temperature Sintering

Cells are densified and microstructures are formed through precisely controlled sintering.

Key points:

  • Advanced thermal profiles
  • Electrolyte densification
  • Optimized electrode porosity

Step 5 — Cell Evaluation & Quality Control

Each cell undergoes performance validation before delivery.

Key points:

  • Electrochemical testing
  • Reliability screening
  • Customer-aligned validation protocols
  • Post-Mortem SEM cross-section analysis

Designed for Scale from Day One

VoltaCera’s processes are developed with manufacturability in mind.

Our production strategy focuses on:

  • Process reproducibility
  • Batch-to-batch consistency
  • Manufacturing scalability
  • Industrial equipment compatibility

We design processes not only to work — but to scale.

What This Means for Partners

Working with VoltaCera provides partners with:

  • Faster design iteration cycles
  • Reliable supply of high-quality cells
  • Reduced technology transfer risk
  • Direct collaboration with the manufacturing team
