Systems for electrocatalysis and fuel cells

Thanks to our modular system design, we can offer you flexible and customizable test units for electrocatalysis and fuel cells that match your specific needs. Our parallelized systems guarantee identical conditions for electrocatalyst and cell component testing. They also enable fast, comparable, and reproducible results thanks to the use of a single common infrastructure.  

Identical test conditions guaranteed

The research field of electrolysis and fuel cells holds significant innovation potential. However, developing new electrocatalytic processes requires testing a wide range of parameters. In addition to typical process parameters such as pressure, temperature, feed composition, and flow rate — electrochemical systems introduce further variables, including current density, applied potential, surface resistances, and diffusion effects in membranes. Some of these are more challenging to control and compare.

At hte, we support research and development teams in managing this complexity and obtaining reliable results more efficiently. Our systems enable parallel operation of multiple electrochemical cells — from compact 4-cell units to high throughput setups with up to 16 cells. Unlike serial test systems, they ensure identical test conditions across all cells and enable direct comparison of results while generating larger datasets.

With our range of laboratory systems and modular system design, we offer flexible and configurable test setups for electrolysis and fuel cell research, tailored to specific experimental requirements.

  • Water electrolysis (PEM, AEM, AWE)
  • Co-electrolysis

From high throughput research to electrocatalyst testing

At hte, we are the world’s leading solution provider of lab-scale R&D workflows. We also have extensive application know-how in the field of high throughput research. We have applied this knowledge and our technology platform for heterogeneous catalysis to electrocatalyst testing:

  • Parallel screening of up to 16 electrochemical cells 
  • Test systems can also be revamped, for example switching over from PEM electrolysis to AEM electrolysis or from gap operation to zero-gap operation 
  • hte test systems are compatible with all in-house and commercial cells
  • hte-cells are based on a modular system that can be modified, for example by installing gas diffusion electrodes (GDE) 
  • Automated system for 24/7 operation  
  • Modular system design of the test units with customizable laboratory footprint (parallel, L-shape) 
  • Test systems can be extended at a later date, for example by adding another reactor rack with the option of running additional test cells 
  • User-friendly software operation (integration of electrochemical analytics in the test control software) 
  • Specific electrochemical analytics  
  • Automatic electrolyte mixing and dosing possible

We support your projects with structured methodologies, including material screening and process development to rapidly narrow down promising candidates. Durability is assessed via accelerated stress tests (ASTs) as well as long term testing for application relevant lifetimes. Dynamic load protocols complement these approaches by simulating real operating conditions and enabling robust comparability of results.
