With the ongoing global market introduction of fuel cell systems for mobility and for stationary applications, the need for testing and characterisation is rising, as too is the demand for independent test centres.

In order to meet this demand, ZSW has continuously expanded its fuel cell test field established 20 years ago and now operates one of the largest test fields worldwide for fuel cell stacks up to 160 kWel output.

Issues such as the electrical properties of fuel cells under the dynamic load conditions that can occur in everyday driving use are critical for fuel cells in road traffic. Fuel cell modules with hydrogen or hydrogen mixes ranging from 100 W to 100 kWel can be evaluated for suitability.

The test centre in Ulm has around 25 test benches where 24/7 endurance tests can be performed.

// Qualified tests of cells, stacks, systems, and system components

Fuel cells, fuel cell stacks, fuel cell systems and components of fuel cell systems are investigated and characterised professionally, reliably and dependably at ZSW; this includes qualified test analyses and the identification of optimisation parameters.

The test benches can run fully automatically in 24/7 operation. They are highly flexible and allow all customer requirements to be implemented. Even tests in accordance with prescribed procedures such as DIN IEC 62282-2 can be implemented in conjunction with an Approved Supervisory Authority.

As the interpretation of test results requires an extremely in-depth understanding of the interaction of materials and components in cells, the tests are supplemented by a variety of analysis devices and methods and test-supporting simulations.

// Design and construction of test benches

ZSW has been developing and building fuel cell test benches for standard and special applications for 20 years. These test benches are regulated using a proprietary, proven and user-friendly control program with integrated data acquisition.
