Automated Fuel Cell Catalyst Discovery and Optimization


MULTIPLANT / AUTOPLANT ENERGY

The cutting edge Process Development Workstation Technology allows scientists to truly mimic
the final industrial production process and provides all the flexibility to optimize integrated reaction sequences, even if a complex configuration of reactors and feed vessels required.

Robustness and ease-of-use by design

The leading technology in overhead gravimetric dispensing / dosing (patented) combined with our quality by design reactor and process excellence, and our user-friendly software, allow you to accelerate, standardize and digitalize your fuel cell catalysts and membrane discovery as well as optimization workflows.

Key advantages
