In our last newsletter we featured the THDA (Total Harmonic Distortion Analysis), the measuring technology drawing on cell voltage for monitoring fuel cell stack operation. In INN-BALANCE, the integration of the THDA into a Fuel Cell Electric vehicle for constant online surveillance of the stack is being evaluated by AVL. Jan Schmidt from AVL already talked about the overall concept of the THDA in the newsletter’s exclusive interview. In this video series he further explains why the THDA is the most advanced method currently available for reducing fuel cell stack degradation and reveals more of the work that is being done in INN-BALANCE.

About Total Harmonic Distortion Analysis
In automotive applications quick adjustments of fuel cell operations are particularly important. Facilitating smooth driving in different modes, while also ensuring durability of the fuel cell stack, requires a flexible operation strategy that prevents harmful conditions like elevated humidity, which inhibits the reaction of hydrogen and oxygen inside the stack. With the information provided by THDA, operations of automotive fuel cell stacks can be adjusted in order to avoid harmful conditions that damage the fuel cells and increase the degradation of the stack.
