Abstract:
A system for communicating measurement data from each fuel cell or a group of fuel cells in a fuel cell stack, including a plurality of fuel cells and a plurality of stack plates, where one stack plate is between each fuel cell and on each end of the stack. The system includes a plurality of embedded smart plates where each embedded smart plate is mechanically and electrically coupled to at least one of the plurality of stack plates, and where each embedded smart plate includes optical transceivers on a top side and a bottom side of the smart plate. The system further includes at least one aggregator device having at least one optical transceiver to initiate a series of communications between the embedded smart plates to determine the location and data collected by each of the smart plates.

H02J 7/00
H02J 7/00
US Classification:
320101, 320104, 320138, 320139
Abstract:
A system that monitors fuel cells in a fuel cell group. The system includes a plurality of voltage sensors coupled to the fuel cells in the fuel cell group, where each sensor monitors a different voltage of the fuel cells and where lower priority voltage sensors monitor higher voltages and higher priority sensors monitor lower voltages. The system also includes a plurality of oscillators where a separate oscillator is coupled to each of the sensors. Each oscillator operates at a different frequency where higher frequency oscillators are coupled to lower priority sensors and lower frequency oscillators are coupled to higher priority sensors. A light source that receives frequency signals from the oscillators and switches on and off in response to the frequency signals. A light pipe receives the switched light signals from the light source and provides light signals at a certain frequency at an end of the light pipe.

Assignee:
GM GLOBAL TECHNOLOGY OPERATIONS LLC - Detroit MI
International Classification:
H01M 8/04
US Classification:
398140, 429432
Abstract:
An integrated environmental barrier for protecting the receiver portion of a fuel cell stack health monitoring system. The stack health monitoring system includes a transmitting measurement module and an optical communication module having a receiver. Measurements indicating the health of the fuel cell stack are optically communicated between the transmitter and receiver through the environmentally protective barrier. The environmentally protective barrier is disposed between the measurement module and the optical communication module such that the environmental barrier isolates the optical communication module from the environment contained within the fuel cell stack. The environmental barrier comprises light blocking and light transmitting portions enabling system variation while ensuring signal integrity.
