Our leading-edge test equipment, software, components, and services are offered as individual modules or turn-key, fully customized solutions - addressing many test industries including sensor testing, materials testing, catalyst evaluation, laboratory automation, and fuel cell testing.

In the field of fuel cells, since the 1990s our fuel cell test stations have been used around the world on fuel cells and subsystems of all sizes (from milliwatts to 150 kW), all chemistries (e.g., PEMFC, SOFC, DMFC), all types (micro, small, large), and many fuels (hydrogen, diesel, natural gas, gasoline, reformate, etc.).

We continually provide our customers with the most innovative testing equipment available. We were the first to offer computer-controlled, automated fuel cell test stations. We were the first to offer ultra-low impedance electronic loads, the first to offer a graphical user interface, the first to offer full automation through scripting, and the first to offer dozens upon dozens of other novel testing features and capabilities.  If you are ever going to see a feature or capability in testing equipment, chances are you will see it in Fideris Brand testing equipment first.
