Verifying each R&D approach requires a measuring technique tailored to the specific development and the processes involved.
IEK-3 therefore has measuring techniques and facilities for all four R&D priorities (DMFCs, HT-PEFCs, SOFCs and fuel gas production) on the cell, stack, reformer and system scale. The measurement results are evaluated using analysis results as well as by modeling and simulation.
Cell development focuses on the optimization of the MEA components by improving the design of the individual functional layers with respect to media transport, electrical properties and feasibility of production as well as characterizing the properties of the modified cell. This will have a positive impact on performance, degradation and costs..
Stack and Reformer
The development of stacks and reformers comprises much more than measuring technology. Before a stack or reformer can be tested, it passes through the essential steps of its production, such as design, construction, manufacturing and assembly. Subsequently stack and reformer be subjected to extensive functional tests as well as specific tests for performance and lifetime. Testing procedures were developed specifically for each envisaged application.
Systems are measured to demonstrate that they fulfill requirements with respect to function, performance and lifetime. The degree of hybridization with a suitable battery module is an important factor for dimensioning the fuel cell stack as well as for the operational mode of the system. In addition to hybridization, IEK-3 also carries out research into coupling fuel cell systems and systems for fuel processing from middle distillates and testing the coupled systems.
