With the ongoing worldwide market introduction of fuel cell systems for mobility or for stationary applications, the need for testing and characterization is increasing - and with it the demand for independent test facilities. For example, the focus of fuel cells in vehicles is on their electrical behavior under dynamic load conditions such as those that can occur in the daily driving cycle.

In order to be prepared for this, ZSW has continuously expanded the fuel cell test field established 20 years ago. With more than 30 fully automated test benches, we now operate one of the world's largest independent test fields for fuel cell stacks with an output of up to 160 kWel. 

Furthermore, fuel cell modules with hydrogen or hydrogen mixtures from 100 W to 100 kWel can be tested for their suitability. With our test benches, cost-effective round-the-clock endurance tests can be carried out.

// 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 25 years. These test benches are regulated using a proprietary, proven and user-friendly control program with integrated data acquisition.
