Through-stack communication method for fuel cell monitoring circuits
A system and method for monitoring fuel cells in a fuel cell group. The system includes a sensor circuit, such as a voltage sensor circuit, that monitors a condition of the fuel cells. If the sensor circuit detects a low performing cell, then it sends a signal to a tone generator that generates a frequency signal that switches a load into and out of the cell group. A voltage sensor detects the voltage of the cell group including the frequency signal, and sends the detected voltage signal to a tone decoder that decodes the frequency signal to determine that the fuel cells are low performing.

The valve includes a valve plate and coupling plate that are cooperative with one another within a valve body such that flexural forces imparted to the valve plate from a pressurized fluid are transferred to localized contact surfaces between the valve plate and coupling plate. By concentrating these forces to such a localized area, improvements in the ability of the fluid to initiate and propagate a crack in built-up ice around the valve's seating region is improved. In this way, fuel cell starting in cold conditions—such as those associated with temperatures at or below the freezing point of water—is also improved.
