Cathodes

One backing. A family of cathodes.

Each cathode is defined by the catalyst it carries.

Strato-X^™ cathode

Strato^™ + Catalyst = Cathode

What it is

Strato^™ plus a partner catalyst
A multi-layer construction. Strato^™ contributes a carbon-based backing bonded to a metal mesh, and the partner catalyst is applied above it in multiple fine passes to form the active layer, where the electrochemical reaction takes place.
A family of cathodes
One backing supports a growing family of cathodes. Strato-X01^™ and Strato-X02^™ are available to qualified customers today, and partner catalysts extend the family further.
Flexible and conformable
Each cathode inherits the mechanical resilience of Strato^™, holding its catalyst layer intact as it bends and conforms to the cell.

Flexible and strong

Bends without cracking.

Strato^™ flexes with the cell and retains catalyst-layer adhesion under repeated flexing through handling and assembly.

Strato^™ + catalyst A = X01^™

Strato^™ + catalyst B = X02^™

Cathode

Strato-X01^™

Vulcan XC72 carbon support. Highest performance at high current density, specified for CO₂-controlled environments.

Cathode

Strato-X02^™

Graphitized carbon support. Higher durability in CO₂-rich environments, with a modest trade-off in high-current-density performance.

Applications

Built for systems that breathe.

Velara cathodes are engineered for deployable electrochemical energy systems in which the cathode sets performance and service life. Strato^™ is validated in high-humidity electrochemical systems under high-load conditions, the environments these systems operate in.
