STACK-POWERED FUEL CELL MONITORING DEVICE WITH PRIORITIZED ARBITRATION |
摘要 |
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.
