The invention disclosed herein relates to fuel cell electrode pair assemblies, not having interposing proton exchange membranes, configured to receive and react with liquid anolyte and liquid catholyte microfluidic flowstreams. In accordance with the present invention, the compounds of the invention comprise:. The detection system comprises at least one sensor for measuring a force experienced by the rotary tool or a parameter related to the force experienced by the rotary tool during processing, wherein the sensor provides sensor signals. When a request to disengage the form-locking shift element occurs, a disengagement control signal is generated and the form-locking shift element is actuated in the direction of disengagement, depending on the disengagement control signal. The computer file may be used by the potential user to analyze the capabilities of a computer system relative to the set of requirements for the application program.
