Abstract
In certain configurations and applications, fuel cell stacks can be subject to damage arising from resonance. For instance, the natural frequency of lengthy automotive fuel cell stacks can be low enough to be problematic. Incorporating appropriate support bars between the compression straps holding such stacks together and the fuel cells in the stack can suitably increase the natural frequency in a relatively compact manner.
